[0019] Example 1, as Figure 1-2 As shown, this utility model discloses a handheld simulated lightning generator, comprising a main unit module 1, a discharge module 2, a display and control module 3, a communication module, and a battery compartment 4. The main unit module 1, serving as the core control unit of the device, includes a housing. The housing houses a microprocessor, a safety detection circuit, a charge / discharge management circuit, an impulse voltage generation circuit, and a high-frequency switch drive circuit. The housing is made of insulating shielding material to prevent external electromagnetic interference and ensure operational safety.

[0020] Circuit diagram as follows Figure 4-8The microprocessor uses a GD32F103C8T, the safety detection circuit uses a BQ29700 to implement battery overcharge, over-discharge, overcurrent, and short circuit protection, the charge and discharge management circuit uses an ETA6003 battery charger, a TPS61088 boost converter, and an impulse voltage generation circuit that doubles and rectifies the input voltage and generates a pulse signal with a certain duty cycle under the control of the microprocessor to drive the IGBT to achieve impulse voltage discharge. The high-frequency switch drive circuit uses a TLP250 optocoupler driver.

[0021] Specifically, the battery in this device is charged using an ETA6003 capacitor and boosted by a TPS61008 voltage booster. The voltage after passing through a voltage doubler rectifier circuit serves as the input to the impulse voltage generation circuit. The microprocessor, a GD32F103C8T, generates a pulse waveform signal with a specific duty cycle by setting internal PWM parameters. This signal drives the IGBT switch via a TLP250, simulating the charging and discharging of the high-voltage capacitor in the impulse voltage generation circuit, thus mimicking a lightning impulse voltage wave. The safety detection circuit uses a BQ2970 to monitor parameters during battery charging and discharging, providing overcharge, over-discharge, overcurrent, and short-circuit protection.

[0022] The microprocessor is electrically connected to the charge / discharge management circuit, the safety detection circuit, and the high-frequency switch drive circuit. The charge / discharge management circuit is also electrically connected to the battery and the impulse voltage generation circuit. The impulse voltage generation circuit is electrically connected to the high-frequency switch drive circuit. The high-frequency switch drive circuit is electrically connected to the discharge module 2. The microprocessor transmits signals to the discharge network of the discharge module 2 through the mechanical and electrical interface.

[0023] The main unit module 1 is the core of the device. Its upper surface houses the display and control module 3, and its lower part contains the battery compartment 4. The end of the battery compartment is detachably connected to the discharge module 2 via a standard mechanical and electrical interface. It also integrates a communication module. This design aims to achieve device integration and portability. Its advantages include centralized signal control and power management, improving the overall structural compactness and field applicability.

[0024] Discharge module 2, a key component for generating high-voltage pulses, integrates an energy storage capacitor and a discharge resistor. These capacitors and resistors are connected in series to form a discharge network, supporting various combinations, such as a 150pF energy storage capacitor with a 330Ω discharge resistor, or a 100pF energy storage capacitor with a 1500Ω discharge resistor. Module 2 is located at the external interface of the main module 1 and is inserted into the main module 1's interface via a mechanical-electrical interface, such as a DB9 connector. The DB9 connector has a locking function, securing it to the bottom to prevent accidental dislodgement. The two metal heads of discharge module 2 are electrically connected to the two ends of the discharge network, forming a discharge channel that supports both contact discharge and air discharge. Its purpose is to achieve various waveform simulations through replaceable modules, offering advantages such as simple operation, accurate and reliable waveforms, and avoiding the limitations of fixed circuits.

[0025] The discharge voltage can reach 10kV. If a 150pF / 330Ω discharge module is used, the RC time constant (τ) = RC, τ = 49.5ns; the peak current (I... peak )≈V / (R+R eut During discharge, R eut If it is very small, then: I peak ≈30.1A. Stored energy (E) = (1 / 2)CV 2 =1.5mJ, V=sqrt(2E / C)=10kV.

[0026] The display and control module 3 is located on the surface of the main unit module 1 and includes a display screen, a run button, a voltage adjustment button, and a polarity switching button. The display screen, located in the center of the display and control module 3, displays real-time voltage, polarity, pulse count, and battery status information. The run button is used for power-on and power-off operations. The voltage adjustment button and polarity switching button are used for parameter adjustment. These buttons and the display screen are electrically connected to the microprocessor within the main unit module 1 via internal signal lines, enabling the transmission of user input signals and feedback of status information. Its purpose is to provide an intuitive interactive interface, facilitating real-time on-site monitoring and parameter adjustment, and improving operational efficiency and safety.

[0027] The communication module includes a serial communication interface, located at the bottom of the host module 1's housing and electrically connected to the microprocessor. It connects to a host computer to enable remote control and data monitoring signal transmission. Its purpose is to expand the device's control capabilities, offering advantages such as support for data recording and remote operation, suitability for complex testing scenarios, and enhanced device versatility.

[0028] The battery compartment 4 houses a lithium battery located inside the lower part of the main unit module 1. It is electrically connected to the charge / discharge management circuit and connects to an external charger via a charging interface on the main unit module 1 housing. The lithium battery supplies power to the impulse voltage generation circuit and the high-frequency switching drive circuit through the charge / discharge management circuit, achieving independent power supply. This aims to eliminate dependence on an external power source, offering advantages such as support for extended field operations and improved device mobility and portability.

[0029] The working principle of this device is as follows: First, the lithium battery in the battery compartment 4 is powered by the charge / discharge management circuit. The microprocessor receives user input signals from the display and control module 3, such as voltage, polarity, and trigger mode settings. Then, the charge / discharge management circuit controls the impulse voltage generation circuit and the high-frequency switch drive circuit to generate high-voltage pulses. This pulse signal is transmitted to the energy storage capacitor and discharge resistor of the discharge module 2 through the mechanical-electrical interface, forming a discharge channel between the two metal heads to simulate a lightning waveform. Simultaneously, the microprocessor records the pulse count and displays the status information on the display screen, supporting automatic voltage increase in gradual change mode. If remote control is required, data can be exchanged with the host computer through the communication module. This workflow enables portable high-voltage pulse generation, ensuring the immediacy and accuracy of the test.
