Energy controller for conversion from a direct current source to a variable frequency load

摘要

A turn off circuit for a multiphase motor is provided comprising a DC powered system including a three element core having a central core element and an inner and outer core element coupled thereto. A series of capacitors are connected to an outer core element to discharge simultaneously and turn off positively and negatively biased SCRs which sequentially fire and produce a suitable pulse width and frequency to the motor. A control system is provided to produce a variable pulse frequency and pulse width to a power circuit which sequentially fires and admits battery power to the motor.
