This reference design implements a digitally-controlled, 500-W, two-phase interleaved LLC resonant converter. The system is controlled by a single, C2000 microcontroller (MCU), TMS320F280025C, which also generates pulse width modulation (PWM) waveforms for all power electronic switching devices under all operating modes. This design implements an innovative current sharing technique to accurately achieve current balancing between phases.
