Abstract:
Apparatuses and methods are described for implementing adjustable speed drives. For instance, an apparatus may comprise an inverter circuit configured to drive a multi-phase electrical load, the inverter configured to be powered by first and second direct-current (DC) bus lines, a fan drive circuit configured to be powered by the first and second DC bus lines, a fan configured to be controlled by the fan drive circuit and having a plurality of windings coupled together at an electrical node, a first capacitor having a first terminal coupled to the first DC bus line and a second terminal coupled to the electrical node, and a second capacitor having a first terminal coupled to the second DC bus lines and a second terminal coupled to the electrical node.
