UCD3138: How to improve the efficiency of full-bridge hard-switching power supply based on UCD3138

Part Number: UCD3138


Hello, I modeled the UCD3138 full-bridge hard-switch demo board to make a 24V input 5V40A output power.

Now that the main power supply function has been achieved, but the efficiency is only 84%, which is less than 92% of the development board.

Which aspects should I optimize to improve the efficiency of the circuit? Is there a related application document recommendation?

Looking forward to your reply
