Circuit board unit for driving and controlling motor that drives compressor for air-conditioner |
摘要 |
A circuit board unit for driving and controlling a motor that drives a compressor for an air-conditioner has a first mounting base, a second mounting base mounted on the first mounting base, and a printed circuit board mounted on the second mounting base. The first mounting base has thereon a first group of high voltage electrical elements belonging to a motor driving circuit and a heat sink so that some of the high voltage electrical elements that need positive heat dissipation are mounted thereon. The second mounting base has thereon a second group of high voltage electrical elements belonging to the motor driving circuit and a plurality of flat electrical conductors that are partially embedded in the second mounting base in an insert mold fashion and forming a predetermined wiring pattern so as to electrically connect the high voltage electrical elements. The printed circuit board has thereon a group of low voltage electrical elements belonging to a motor control circuit.
