Chapter 3

Synthesizing Phase-shift Bidirectional DC/DC Converters

Outline

1. Review of phase-shift controlled bidirectional DC-DC
2. Switch Cell
3. New family of phase-shift bi-directional DC-DC
4. Example:build new phase-shift bi-directional DC-DC
5. Summary

How do we get square-wave voltage source?

In non-isolated bidirectional DC-DC converter,the voltage waveform across the inductor is square wave when the duty cycle is 50%.

Summary

A technique to generate phase-shift bi-directional DC-DC converter is proposed.

Example of deriving new bi-dc/dc is presented.

All switches achieve ZVS in both the forward mode and the backward mode in thery.
