摘要: | In high switching frequency and low duty conversion, the on-time in duty cycle is restrained to brief period. The three-level converter extends the on-time to two times larger. By Pseudo-Ramp Controller (PRC) and Auto-Ripple Cancellation (ARC) Topology, flying capacitors are balanced to 50% input voltage with the accuracy of duty cycle improves 11 times and 3mV output voltage ripple. |
