Abstract
PURPOSE: To carry out the proportional control of capacity corresponding to load by using an inverter consisting of a forward converter, a chopper, a reverse converter, the speed instructing circuit of a motor, and a torque limiting circuit.
CONSTITUTION: Three phase 200 volt AC from the commercial power source 11 is rectified and smoothed by a forward converter 12, and changed to DC voltage. This DC voltage is changed to a DC voltage corresponding to the input signal of a chopper regulating circuit 22 by the action of a chopper 16. Transistors 24 - 29 in a reverse convent 23 turn on and off at mutually related cycles and generate three phase AC voltage, and this voltage is supplied to motor 4. A torque limiting circuit 38 limits the running torque of a compresor 3 so as not to exceed a specified value. A speed instructing circuit 41 gives speed instructing signals to control the revolution speed of the compressor 3, based on the temperature signals from a thermistor 42 and the room temperature setting signals from a variable resistor 43.
