<p>The invention provides a small, low-cost power controller for a refrigeration system. A first substrate (1) of high cooling efficiency on which an inverter circuit is mounted and a second substrate (4) on which a control circuit is mounted are arranged in parallel in a case (9). The case (9) has slits through which a heat sink (2) and a connector (6) extend outside the case. The case (9) is fixed to a compressor with a fixture (11). This structure allows the power controller to be integrated with the compressor with best cooling efficiency, thus saving space in the refrigeration system.</p> |
