Half-Bridge Driver with Inbuilt Oscillator
https://www.electronics-lab.com/project/half-bridge-driver-with-inbuilt-oscillator/
This project is a Half Bridge with Inbuilt Oscillator utilizing the NCP1392B MOSFET driver and IRF540 MOSFETs for half-bridge topology applications. It allows for adjustable operating frequency from 25 kHz to 100 kHz with a trimmer potentiometer. The project includes brown-out protection, a PFC delay timer, and fixed dead time to improve performance. Designed for low-voltage applications up to 36V and 3A load current with forced air cooling, it can be modified for high-voltage use up to 400V by changing components like capacitors and MOSFETs. The operating frequency can be tuned up to 480 kHz depending on component values, with recommendations to consult the datasheet for optimal performance in higher frequency applications.
