Abstract
PURPOSE:To suppress the pulsation of motor coal winding current and enable the switching element of a small current capacity to be used, by controlling the coil winding current when the coil winding current exceeds a previously set limit value. CONSTITUTION:A controller is composed of a compressor 1, a compressor driving brushless-motor 2, a power module section 3, a power circuit section 4, and a control circuit section 5. When current detected by a coil winding current detecting circuit 5g in the control circuit section 5 exceeds a limit value, then by a current limiting circuit 5f, the signal of a drive circuit 5c is interrupted, and coil winding current is limited.
