  • Patent number: 11699972
    Abstract: The present disclosure includes techniques for implementing a variable speed drive (VSD) in an environmental conditioning system to facilitate mitigating or eliminating system faults. The variable speed drive drives a motor during on-cycles and heats motor windings of the motor during off-cycles. The variable speed motor drive includes a rectifier that converts alternative-current (AC) power input to a direct-current (DC) power output, a DC bus that is coupled to the rectifier and includes a DC bus transistor, and an inverter. The DC bus transistor pre-charges a DC capacitor of the DC bus to drive the motor during on-cycles and receives a gate pulse with a duty cycle based on a differential temperature, where the gate pulse heats the motor windings. The inverter receives the gate pulse applied to the DC bus transistor and transmits it a motor winding to prevent moisture on the motor winding.
