Abstract
A novel minimum-voltage active-clamping (MVAC) PFC controller was developed, which is capable of providing effective control scheme to the MVAC PFC converter to suppress the reverse-recovery current of the boost diode and minimize the voltage stress on switch devices. The corresponding control strategy was proposed and implemented in its design. To reduce the ripple currents in output capacitor, the leading-edge modulation was employed. And programmable turn-on delay time was adopted to realize zero-voltage-switching (ZVS) operation. The IC was designed and simulated in 1.5 /spl mu/m BCD (bipolar-CMOS-DMOS) process. The simulation results showed that the expected specifications were achieved.
