[0002] Low-frequency (10 kHz to 100 kHz) radio signals propagate in the Earth-ionosphere waveguide, with characteristics such as stable propagation, being unaffected by nuclear explosions and ionospheric disturbances, and having low attenuation during propagation in the atmosphere, making them suitable for long-distance and underwater communication and navigation. Ground-based fixed low-frequency transmitting stations are large in scale and high in construction cost, and the low-frequency transmission power usually reaches 200 kW to 2000 kW.

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] The terms "first", "second", "third", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0037] Figure 1 It is a schematic diagram of a low-frequency high-power signal continuous emission system provided by an embodiment of the present application, as Figure 1As shown in the figure, a low-frequency high-power signal continuous emission system provided by an embodiment of the present application includes a high-voltage DC power supply, a signal processing unit, a plurality of power amplification units, a plurality of output transformers, a plurality of power switches, a plurality of output switches, a parallel connection bus, and a power synthesis control system;

[0038] The number of power amplification units, output transformers, power switches, and output switches is the same;

[0039] The signal processing unit is connected to all power amplification units, and is used to input the externally input low-frequency excitation signal into each power amplification unit respectively. The low-frequency excitation signals input into each power amplification unit are the same;

[0040] The high-voltage DC power supply is connected to the plurality of power amplification units via a plurality of power switches, and each power amplification unit is respectively connected to a power switch;

[0041] Each power amplification unit is respectively connected to an output transformer, each output transformer is respectively connected to an output switch, all output switches are connected to the parallel connection bus, and the parallel connection bus is used to be connected to an antenna to transmit the processed low-frequency signal;

[0042] Each power amplification unit is respectively connected to the power synthesis control system, and the power synthesis control system is used to monitor the operation status of each power amplification unit.

[0043] Specifically, a low-frequency high-power signal continuous emission system provided by the present application mainly consists of a high-voltage DC power supply, a signal processing unit, n power amplification units (1#, 2#,..., n#), n output transformers (B1, B2,..., Bn), n power switches (Ki1, Ki2,..., Kin), n output switches (Ko1, Ko2,..., Kon), a parallel connection bus, and a power synthesis control system, and adopts parallel connection power synthesis of output transformers. Obviously, the power amplification units, output transformers, power switches, and output switches correspond one by one, and their numbers are the same.

[0044] The signal processing unit distributes the excitation signal from the exciter into n optical excitation switch signals with dead zones, and transmits them to the n power amplification units through optical fibers, which can isolate the electrical interference between the power amplification units and the signal processing unit.

[0045] Each power amplification unit first converts the received optical excitation switch signal into an electrical signal, and then amplifies the power in a switching amplification manner through a high-power H bridge. Optionally, a power amplification tube with a withstand voltage of 1200V and a current of 600A can be selected. When the output is 100kW, it can work at a voltage of 600V and a current of 200A, and has sufficient power capacity to withstand the power redistribution power fluctuation caused by the failure of a single power amplification unit, and the instantaneous current surge will not impact the power amplification unit.

[0046] The output transformer is used for impedance matching between the power amplification unit and the antenna impedance. According to the power level, the input-output ratio of the output transformer can be from 1:3 to 1:10, reducing the highest voltage that the power amplification unit has to bear and boosting the output voltage to 1.8 kV to 6 kV. To ensure the output power balance of each power amplification unit, the input-output ratios of n output transformers need to be controlled within ±0.2% of consistency.

[0047] n power switches are connected to the high-voltage DC power supply, and the DC voltages on the n switches are the same. Each power switch, power amplification unit, output transformer, and output switch are connected in series in turn to form a power amplification channel. The secondaries of the n power amplification channels are connected in parallel and aggregated to the parallel bus and then connected to the antenna device.

[0048] The parallel bus can select copper tubes with a diameter of 50 mm to 200 mm according to the power level, capable of withstanding low-frequency high powers from 200 kW to 2000 kW.

[0049] To ensure the output balance of the power amplification unit, the parameters of the n output transformers through which the n power amplification units pass need to be as consistent as possible. Since the n power amplification units share a high-voltage DC power supply, it is easy to ensure the consistency of the output voltages of the n power amplification units, and the consistency of the output transformer parameters is particularly important.

[0050] The power combining control system detects the power amplification unit and controls the closing and opening of the electronic switch, DC power switch, and output switch in the power amplification unit. When a certain power amplification unit fails, due to the secondary parallel connection method of the output transformer, the voltage applied to the antenna and the antenna load remain unchanged, and the full-power output power is instantaneously and evenly redistributed to the remaining n - 1 groups of power amplification channels. At this time, the output voltages of the remaining groups of power amplification units remain unchanged, only the output current increases, and the voltage applied to the antenna device and the antenna load remain unchanged, without affecting the external output power.

[0051] Due to the redundant design of the power amplification unit, that is, each power amplification unit can withstand a power amplification task higher than the actual situation, the instantaneous current consumption will not cause an impact on the system. At the same time, after the power combining control system detects a failure of the power amplification unit in real time, the power combining control system sends a signal to disconnect the electronic switch, DC power switch, and output switch in the power amplification unit, so that the faulty power amplification unit is completely disconnected from the transmitting system, blocking the influence of the faulty unit on the antenna load power and completing the signal transmission without power reduction.

[0052] A low-frequency high-power signal continuous emission system provided by an embodiment of the present application, through the adoption of parallel power amplification and synthesis, when a single power amplification unit fails and exits, the total power automatically distributes the power of the remaining power amplification units, and relies on the redundant output capacity of the remaining power amplification units to keep the total output power continuously unchanged, avoiding the problem of the output power decreasing when a single power amplification unit in series power synthesis fails, and improving the reliability of the continuous operation of the emission system.

[0053] Optionally, in the low-frequency high-power signal continuous emission system provided by the present application, when the power synthesis control system detects that a certain power amplification unit fails, it controls to disconnect the power switch and the output switch connected to the power amplification unit.

[0054] Optionally, in the low-frequency high-power signal continuous emission system provided by the present application, the rated power of each power amplification unit is P', and there are n power amplification units in total. The rated power of the low-frequency high-power signal continuous emission system is P = (n - 1)P'.

[0055] Optionally, in the low-frequency high-power signal continuous emission system provided by the present application, the number of power amplification units is between 3 and 21.

[0056] Optionally, in the low-frequency high-power signal continuous emission system provided by the present application, the rated power of the low-frequency high-power signal continuous emission system is between 200kW and 2000kW.

[0057] The following uses a specific embodiment to illustrate the low-frequency high-power signal continuous emission system provided by the present application:

[0058] In an embodiment, when the rated low-frequency emission power of the system is 500kW, n = 6, and the combined output power is 500kW. The output power of each power amplification unit is 83.3kW. When a single power amplification unit fails and exits, each power amplification unit increases the output power to 100kW by relying on the redundant output capacity, and the system can still continue to output 500kW, ensuring the continuous emission of the low-frequency high-power signal of the system.

[0059] Six power switches are connected to the high-voltage DC power supply, and the DC voltages on the six power switches are the same; the power switch, the power amplification unit, the output transformer, and the output switch are connected in series in turn to form six groups of power amplification devices; the six output transformers are connected in parallel through the secondary of the output switch, and after being connected in parallel, they are connected to the antenna device; the six power amplification units receive the same low-frequency excitation signal output by the signal processing unit, and each power amplification unit can withstand a power amplification capacity of 100kW; the power synthesis control system is connected to the six power switches, the six power amplification units, and the six output switches.

[0060] The power combining control system monitors the power amplification unit in real time. After it detects that the power amplification unit receives a low-frequency excitation signal, it sends a signal to control the closing of 6 power switches, the electronic switches of 6 power amplification units, and 6 output switches, connects the high-voltage DC power supply to 6 groups of power amplification devices. The 6 groups of power amplification devices are connected in parallel through the secondary of the output transformer. Each group of power amplification devices outputs a power of 83.3 kW, combines and amplifies the power of the low-frequency excitation signal to 500 kW, and outputs it to the antenna device.

[0061] When a certain power amplification unit fails and disconnects, since the voltage applied to the antenna device and the antenna load remain unchanged, the 500-kW power amplification task is instantaneously and evenly redistributed to the remaining 5 groups of power amplification devices. Each group of power amplification devices outputs a power of 100 kW. At the same time, after the power combining control system monitors in real time that the power amplification unit fails, it sends a signal to control the disconnection of the electronic switch, the high-voltage DC power switch, and the output switch in the power amplification unit, so that the faulty power amplification unit is completely disconnected from the transmitting system, blocking the influence of the faulty unit on the antenna load power, and completing the continuous signal transmission without power reduction.

[0064] The power amplification unit converts the received excitation signal into an electrical signal, and amplifies the power in a switching amplification manner through a high-power H-bridge.

[0065] The output transformer matches the impedance of the power amplification unit with the antenna impedance, reduces the highest voltage borne by the power amplification unit, and increases the output voltage.

[0066] The power-amplified signal is aggregated and transmitted to the antenna via the output switch and the parallel bus for signal transmission.

[0067] Optionally, for the method for continuously transmitting low-frequency high-power signals provided by the present application, when a certain power amplification unit fails, the power combining control system sends a signal to disconnect the corresponding power switch and output switch of the power amplification unit, so that the faulty power amplification unit is completely disconnected from the transmitting system.
