Boost power supply having power factor correction circuit
TL;DR: In this article, a boost power supply has a full-wave rectifier driving an inductor, diode, and the parallel combination of a filter capacitor and load, and a shunting switch connected between the inductor and diode is periodically closed to draw current through the induction, thereby charging the inductors.

Forced load sharing circuit for inverter power supply
TL;DR: In this article, a power supply system that utilizes a plurality of inverter power supplies connect in common to drive a common load with control circuitry for forcing the power supplies to share the load equally is described.
Patent
Dynamic current balancing for power converters
TL;DR: In this paper, a dynamic dead band circuit is incorporated into a pulse width modulation current balance and output voltage regulation control circuit to prevent current imbalance from causing saturation of the power transformer core for all operating conditions of the converter including input voltage falling below its rated low-line value, sudden load surges, or turning off the converter power supply.
