Abstract
The present invention provides an outdoor unit for an air conditioner that can be constructed at low cost while reducing risk of malfunction. The outdoor unit has a compressor; a fan motor; a compressor driver board having a compressor inverter circuit and a compressor driver circuit; and a fan driver board having a fan inverter circuit and fan driver circuit. The compressor driver board has at least either: a shared control circuit that feeds a first switching signal for a compressor to the compressor driver circuit and feeds a second switching signal for a fan to the fan driver circuit; or a shared power source circuit that steps down a first DC voltage to a second DC voltage and supplies the second DC voltage to the compressor driver circuit and to the fan driver circuit.
