Abstract

A motor controller (100) includes a sense and control module (102) used to monitor motor current (110) and voltage requirements to thereby modulate supply current (108) in all four quadrants of the current waveform. An Insulated Gate Bipolar Transistor (IGBT) circuit (106) is driven by a composite pulse derived from the current and voltage waveforms to control the off-time of the resulting power waveform in all four quadrants. A first pulse train is derived from the supply voltage, a second pulse train is derived from the motor supply current, and a composite pulse train is derived from the first and second pulse trains. The composite pulse train is then applied to the IGBT circuit (106) to control off-time as a function of motor load requirements. By closely matching the actual applied current to the actual motor load requirements, the motor's efficiency and lifespan are dramatically improved, and heat generation associated with the motor (120) is greatly reduced.
