100kHz Half Bridge Convertor - SG3525

This is a SMPS Circuit improved over the Application Note in the book SGS Motion Control Application Manual. This worked well. It helps you learn more about High Frequency Power Supply Design.  More details and PCB's Here SG3525 SMPS Project.

100kHz Half Bridge Convertor - SG3525

This was the Module that contained the smps chip. It was done to prevent easy replication by other firms. Also to Keep the Signals isolated from the Main board board currents and Corrosion Prevention by impregnating Module in Epoxy. Yet the main board suffered some corrosion even with some coating protection.
