Description

Technical Field

[0001] This invention relates to the field of pulse power technology, specifically to a high-energy-conversion-efficiency multi-channel electromagnetic induction-coupled LTD driver. Background Technology

[0002] In the field of pulse power technology, linear transformer drivers (LTDs) have broad application prospects in many fields such as industry, medicine, and national defense because they can generate high voltage and high current pulses. With the continuous development of technology, higher requirements are being placed on the energy conversion efficiency and multi-output capability of LTD drivers.

[0003] Traditional LTD drive sources suffer from low electromagnetic coupling efficiency during energy conversion. Due to insufficient optimization of electromagnetic coupling between modules, significant energy loss occurs during transmission and conversion, making it impossible to fully utilize the input energy. This not only increases energy consumption but also limits the output performance of the LTD drive source. Furthermore, traditional drive sources are inadequate in energy distribution and synchronization control among multiple outputs, making it difficult to meet the needs of high-precision and high-reliability applications. Summary of the Invention

[0004] The purpose of this invention is to provide a high energy conversion efficiency multi-channel electromagnetic induction coupling LTD driver source, which has the advantages of enhancing the primary energy to secondary energy transmission efficiency, reducing energy loss during energy transmission, and greatly improving the electromagnetic induction coupling strength through multi-channel electromagnetic induction coupling.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention coaxially winds a primary coil and multiple secondary coils onto an iron core. Utilizing the high permeability of the iron core, the magnetic field is focused, significantly reducing magnetic leakage. This allows for more efficient transfer of electromagnetic energy from the primary coil to the secondary coils.

This enables each secondary LTD module to acquire energy more evenly. Furthermore, the real-time timing control of the control module ensures optimized energy distribution among the secondary LTD modules, thereby improving the overall energy conversion efficiency of the LTD driver and enhancing its overall operational stability and reliability.

[0025] In this technical solution, the charging power supply 702 can charge the primary energy storage capacitor 701 and generate a high-frequency changing current in the primary coil 11, thereby generating a high-frequency changing magnetic field around the iron core 9. At the same time, the secondary coil 10 can generate a current under the action of electromagnetic induction and charge the secondary energy storage capacitor 401. Meanwhile, the sensor group 802 in the control module 8 collects signals from various parts in real time. The timing controller 801 adjusts the triggering sequence of the switching component 402 according to these signals to ensure that each secondary energy storage capacitor 401 discharges at the appropriate time. When the switching component 402 is turned on, the secondary energy storage capacitor 401 outputs a high-voltage pulse to the external load through the pulse transformer 403, realizing energy conversion and output while effectively enhancing electromagnetic induction coupling and improving energy transmission efficiency.

[0026] Specifically, the output terminal of the charging power supply 702 is electrically connected to the input terminal of the primary energy storage capacitor 701. The output terminal of the primary energy storage capacitor 701 is electrically connected to the input terminals of the primary coil 11 and the sensor group 802, respectively.

[0031] Specifically, an insulating pad 12 is in contact between the bottom of the secondary coil 10 and the top of the primary coil 11, and the middle end of the insulating pad 12 is fitted onto the middle end of the iron core 9.

[0032] In this technical solution, by setting an insulating pad 12 between the secondary coil 10 and the primary coil 11, the two can be insulated and separated to prevent short circuits and other problems, thus ensuring the electrical safety of the system.

[0033] Specifically, an electromagnetic shielding cover 6 is fixedly installed on the top of the mounting base 1 and around the secondary coil 10 and the primary coil 11.

[0034] In this technical solution, by setting the electromagnetic shielding cover 6, electromagnetic shielding protection can be provided around the secondary coil 10 and the primary coil 11, effectively reducing electromagnetic interference, ensuring stable system signal transmission, and improving overall stability and reliability.

[0035] Specifically, there are multiple secondary LTD modules 4, which are evenly distributed in a ring array on the inner surface of the ring mounting bracket 3. The number of secondary LTD modules 4 is equal to the number of secondary coils 10.

[0036] Specifically, both the secondary coil 10 and the primary coil 11 are made of multi-strand enameled wire.

[0037] Specifically, the charging power supply 702 is a high-frequency switching power supply, and the switching component 402 is a thyristor.

[0038] Specifically, sensor group 802 includes a voltage sensor, a current sensor, and a temperature sensor.

[0039] In this technical solution, the sensor group 802 integrates voltage, current and temperature sensors, which can monitor key parameters such as voltage, current and temperature in each module in real time and transmit the data to the timing controller 801. The timing controller 801 uses this data to precisely control the switching component 402, so that the system can be adjusted according to the actual operating conditions, thereby further improving the stability and energy conversion efficiency of the system.
