Abstract
The present invention solves a problem that a power controller be large in a refrigerating system, and provides a compact-size as well as an inexpensive power controller. Highly heat-dissipating first board including an inverter circuit mounted thereon and second board including a control circuit mounted thereon are placed in parallel with each other and accommodated by case . Case has slits through which heat sink and connector can extend outside case , and further has fixing section for fixing case to a compressor. This structure allows the power controller to dissipate heat in an optimum manner and to be downsized, and also allows the compressor to integrate the controller thereinto. A capacity that the controller occupies in the refrigerating system can be substantially reduced.
