Abstract:
FPGAs provide complete flexibility in the digital control of switching power converters. This paper extends an existing DC-DC converter reference design with PWM control to create a new DC-DC converter controller combining PI control for load voltage control with hysteresis control for inductor current control. Model-based design is used to develop from offline simulation to real-time implementation with automatic code generation. The hysteresis controller is shown to reduce switching losses, improve inductor current and voltage control, and use fewer FPGA resources compared to the original PWM controller.
