How to reduce switching power supply power loss
1. ZVS (Zero Voltage Switching), ZCS (Zero Current Switching), etc., which use resonant switches to reduce switching losses.
2. Use the edge resonance (EdgeResonance) represented by the active clamp circuit to reduce the switching loss.
3. The fixed loss is reduced by extending the on-time of the switching element to suppress the peak current.
4. In the case of low voltage and high current, the fixed loss is reduced by improving the synchronous rectification circuit.
5. Use the parallel structure of the converter to reduce the fixed loss.
