Abstract

PURPOSE: To efficiently control the operation of a room conditioner, by combining half speed operation by frequency of half power source frequency by a frequency dividing two phase operation system and the full speed operation by direct driving by a commercial power source.
CONSTITUTION: When gate signals are distributing and applied to thyristors CR1∼ CR12, motor voltage is changed into forms as shown in VA and VB, motor voltage and current wave-forms are converted into wave-forms shown in the figure, the frequency of half line voltage, and a motor is operated at half speed as a two phase motor. The motor is operated a half speed with room temp by a room air conditioner reaches fixed temp, and operated at full speed by direct driving by a commercial power source when starting, thus efficiently controlling the operation of the room air conditioner.
