POWER SUPPLY WITH POWER FACTOR CORRECTION FOR USE WITH CABLE PULLER MOTOR

摘要

A power supply for a cable puller motor provides power to a motor operatively coupled to a cable puller assembly, the motor configured to drive a capstan that provides a pulling force on a pulling line wrapped around the capstan. The power supply is operatively coupled to an AC mains source of power and includes a rectifier configured to rectify AC power provided by the AC mains and a chopper power controller configured to generate a PCM DC output power signal. Also included is a power factor pre-regulator operatively coupled to a DC bus and configured to maximize a power transfer from the AC mains to the motor.
