Smps Schematic Diagram. Thank you for your feedback. Efy team october 5 2019 at 3 46 pm.
Every electronic device or product requires a reliable power supply unit psu to operate it. The schematic of my switching power supply you can see below. Linear topology would be unusable for this power 2400w 2 4 kilowatts so i chose a switching topology of a two switch forward half controlled bridge.
Smps circuit controlled by tms320f28062 ir4427 gate driver.
Its construction is typical for a modern computer psu with mosfet switches and active power factor correction pfc. We will add the components list soon. The switching supply uses igbt transistors and is controlled by uc3845 chip. The diagram below shows a partial schematic of a 450 watt atx power supply.
