Abstract
An AC to DC to AC converter has an input to receive input AC, a rectifier to rectify the input AC to DC, and an inverter to invert the DC to output AC. A load sensor senses load on the AC to DC to AC converter. A fan directs a cooling fluid to the AC to DC to AC converter. A fan control has an input coupled to the AC to DC to AC converter so as to receive DC therefrom, an input coupled to the load sensor, and an output coupled to the fan. The fan control controls the fan at a variable speed in response to load on the AC to DC to AC converter so as to vary the cooling fluid delivered by the fan to the AC to DC to AC converter.
