Abstract

This paper introduces a multiphase hybrid boost converter with digital current-programmed controller for high conversion ratio, voltage step-up applications. The controller provides tight output voltage regulation while maintaining real-time current balancing capabilities for superior thermal distribution and converter efficiency. The controller includes a system governor unit which facilitate additional control aspects that are important for multiphase operation such as phase shedding, soft-start mechanism, and system protection. The SMPS operation is validated experimentally on a four-phase 12V -to-300V multiphase prototype with maximum output power of 250W, power density of 2.5kW/Liter.
