Abstract
A renewable energy source is converted into a desired DC voltage that is delivered to a DC motor controller of a permanent magnet motor. A micro controller monitors the amount of supplied renewable DC having the desired DC voltage, which is delivered to each phase of the motor by turning on FET switches on demand. If the renewable DC available at a given instant is not adequate to power a particular phase of the motor, then the micro controller turns on backup FET switches that are part of an independent drive circuit that is in parallel with drive circuits of the renewable DC power circuit, to deliver to the motor line DC, which is produced from an AC supply that has gone through an AC to DC converter. Once charged, the renewable DC power will power the next available phase of the motor.
