In this webinar we design a phase shift full bridge converter with PSIM utilizing Peak Current Mode Control on the input and an output voltage controller. The control loops are setup for analog control, a conversion for digital control making use of advanced PWM triggering available on the C2000 Piccolo processors processors is also demonstrated.
The converter is initially setup in open loop and frequency sweeps in s-domain and z-domain is being performed to determine the controller parameters. The digital control implementation is being verified with a real time HIL simulation using code generated from PSIM and implemented on an F28069 processor.
The design of the power stage, specifically the design equations covering sizing of the inductors and capacitors, are not the primary objective of this webinar.
Some specific topics covered:
- How to setup a phase shift PWM in PSIM
- How to setup Peak Current mode control
- How to do a frequency sweep with a PCMC current loop
- How to setup a PCMC solution using a C2000 MCU
