Abstract

In this paper, the cascaded voltage and power control is proposed to expand the output voltage range for full-bridge-fed CLLC resonant converter. In first, the CLLC resonant circuit is analyzed based on pulse frequency modulation (PFM) and pulse width modulation (PWM). The output voltage is sensed and the power is calculated to tune the switching period to achieve the wide output range. A 3.0kW prototype circuit is implemented to demonstrate the proposed control.
