This application note introduces phase-shift full-bridge (PSFB) modulation. This is a modulation commonly found in zero-voltage switching (ZVS) converters, a group within the family of soft-switched converters. This application note focuses on how a PSFB modulator is implemented in PSoC. Both analog and digital design variations are explored. In addition there is some light discussion about control approaches.
In addition, this application note assumes that you are familiar with developing applications using PSoC Creator™ for PSoC 5LP. If you are new to PSoC 5LP, please refer AN77759, Getting Started with PSoC 5LP. If you are new to PSoC Creator, go to www.cypress.com/go/psoccreator for information about the world’s leading development environment for programmable mixed-signal systems.
