PSFB is a DC-DC converter uses for step-up or step-down the DC voltage using a high-frequency (HF) transformer.
Most of applications, PSFB uses to step-down.
This is from resonant converter family, so that it operates with soft-switching to reduce the switching losses and improves the efficiency.
- DC – DC resonant converter
- Provides galvanic isolation
- Uses the phase-shift control method
- Achieves soft-switching
- Uses for few hundred watts to several kilowatts power ranges
