ABSTRACT:
A control apparatus for compressor with induction motor includes a microcomputer which evaluates an optimum number of rotations at which an operation efficiency of a compressor becomes a maximum when a frequency of an alternating current electric power applied to an induction motor in accordance with a change of a load. An inverter circuit is controlled by the microcomputer, and therefore, a voltage outputted from the inverter circuit is adjusted such that the induction motor becomes the optimum number of rotations.
