Abstract

PURPOSE: To make a semiconductor controller to enable favorable control in an operating range extending over a wide range by a method wherein an outside cooling piece is connected to a cooling piece equipped to a semiconductor controlling element.
CONSTITUTION: A switching mechanism part 3 and a semiconductor controlling circuit 4 are accommodated in a switch case 2, and the semiconductor controlling element 5 to constitute the circuit 4 is fixed to the cooling piece 6 provided in the case 2. Moreover a cooling piece 6 thereof is connected to the center part of an outside cooling piece 19 formed by bending a metal plate having favorable thermal conductivity in a U-shape. Accordingly temperature rise of the element 5 is suppressed, temperature rise of the circuit 4 in the same case 2 is also reduced, and controlling electric power is enlarged sharply.
