Product Description

The SG3525 LM358 High Current High Frequency Inverter Driver Board is designed for electronics enthusiasts, engineers, technicians, and developers working on high-frequency inverter systems and switching power conversion circuits.

The board incorporates the SG3525 PWM controller, widely used in inverter and switch-mode power supply applications. The SG3525 generates controlled switching pulses that can be used to operate compatible power switching circuits.

The LM358 operational amplifier provides analog signal-processing capabilities that may be used for voltage sensing, feedback, or control functions, depending on the board’s circuit configuration.

With an adjustable frequency range of 13–40kHz, the module offers flexibility for different high-frequency transformer and inverter designs.

This board is intended to function as a control and driver module rather than a complete inverter. External power MOSFETs, a suitable transformer, power supply, protection circuitry, and cooling components may be necessary to build a functional power conversion system.

Applications

1. DIY Inverter Projects: Development of custom DC-to-AC inverter circuits using appropriate external components.

2. High-Frequency Transformer Driving: Control of suitable switching stages used with ferrite-core transformers.

3. Switch-Mode Power Supply Development: Experimentation with PWM-controlled power conversion systems.

4. Power Electronics Research: Educational projects involving PWM generation, switching frequency adjustment, and inverter control.

5. Battery-Powered Inverter Systems: Development of inverter circuits using compatible 12V or 24V DC power sources.

6. High-Power Converter Prototypes: Control-stage development for high-power DC conversion applications.

7. Electronics Laboratory Projects: Testing and studying SG3525-based PWM inverter control circuits.

Important Notes

• This product is an inverter driver board, not a complete 5000W inverter.

• The advertised 5000W rating is not a verified continuous output rating.

• Actual power capacity depends on the external switching components, transformer, supply, wiring, protection circuits, and thermal design.

• At 5000W, even an ideal 24V supply would require approximately 208A, so high-power applications require appropriately engineered power hardware.

• Confirm the board’s wiring diagram, output configuration, and operating limits before connecting external MOSFETs or transformers.

• High-frequency inverter circuits may produce dangerous voltages. Proper electrical insulation and protective measures are essential.
