Abstract
One of the purpose is to obtain a motor drive circuit and an outdoor unit for an air conditioner using the same, which can flexibly support change of a model at a low price and in a small lot without using unnecessary materials, wherein a stress in a soldering part due to self-heating is low, a solder reliability is high, and design constraints are small, while maintaining a low-noise and low-loss power wiring due to lowering inductance. The motor drive circuit according to the present invention, for driving the motor using the converter circuit and the inverter circuit, whereon electronic components making up a converter circuit and an inverter circuit are mounted, which includes a lead frame molded board 100 wherein metal plate leads 37 are molded with a mold resin 36, and a single-sided printed circuit board 31 for a control circuit, and wherein power terminals 30 of the electronic components are connected to the lead frame molded board 100, and control wiring terminals 39 of the electronic components are connected to the single-sided printed circuit board 31.
