Abstract

PURPOSE:To prevent a sliding phenomenon of a clutch by providing a by-pass circuit in a circuit for driving an air conditioning compressor so that battery voltage is directly supplied to a clutch when battery voltage drops. CONSTITUTION:When a switch 11 is turned on, if the voltage Vb of a battery 8 is above a set valve, a transistor 41 is turned on to output (e) an oscillating element 24 through a differentiating circuit 44, an oscillating element 34 and a transistor 25, and transistors 31, 9 are turned on to intermittently turn on an electromagnetic clutch 10 during a set time. When the voltage Vb of the battery 8 is below the set value, a transistor 23 is turned on to cause a short-circuit in a condenser 25 and always output power (e) so that the battery voltage Vb is directly and continuously supplied to the clutch 10.
