PWM and PFM Hybrid Control Method for LLC Resonant Converters in High Switching Frequency Operation

High switching frequency is an effective method to improve power density for LLC resonant converters. However, conventional digital controllers, such as general-purpose digital signal processors and microprocessors, have limited frequency resolution, which induces high primary- and secondary-side cu...
