御できなかった。Conventionally, when controlling the phase of a three-phase induction motor, a C-H motor as shown in FIG. 2 has been used. but,
When the charging voltage of the capacitor 5 is used as a gold gate pulse, the phase difference between the voltage and the power source is a maximum of 90 degrees, and therefore the controllable phase range can only be controlled from 08 to 90 degrees.

広い範囲で変化するととＫなる。As the condensing temperature changes, the voltage converted by the thermistor also changes. By comparing this voltage with a triangular wave synchronized with the reference power supply using a comparator, the voltage change due to the scissor ξ star is converted into a change in the phase of the gate pulse. This phase change is K if it changes in a wide range from 0° to 180° at maximum.
