  • DC-DC converter with flying capacitor pre-charging capabilities
    Patent number: 11722055
    Abstract: The voltage stress is limited across switches in multi-level flying capacitor step-down dc-dc converters during a start-up sequence by a circuit. In one embodiment, the circuit includes a diode that is adapted to prevent reverse current flow during steady state operation, a pull-down switch and a commutation cell, which includes a start-up capacitor and a flying capacitor.

  • CAPACITIVE DIVIDER BASED QUASI HOT-SWAP PASSIVE START-UP METHODS WITH FLYING CAPACITOR PRE-CHARGING FOR FLYING CAPACITOR BASED DC-DC CONVERTER TOPOLOGIES
    Publication number: 20210057999
    Abstract: Embodiments described herein introduce two sets of methods for limiting the voltage stress across switches in multi-level flying capacitor step-down de-de converters during the start-up sequence. Systems, devices, apparatuses, controllers, control methods, and processors are contemplated for an improved power converter topology. The embodiments are designed to aid in reducing the deficiencies noted in respect of ML-FCs, among others.
