Abstract:
A single-phase AC motor control circuit for a dryer, including a starting control unit, a first drive circuit, a bidirectional triode thyristor BCR1, a second drive circuit, and a bidirectional triode thyristor BCR2. The bidirectional triode thyristor BCR1 is serially connected to a motor starting winding, and a starting capacitor, and then to a utility power AC input. The starting control unit is connected to a control end of the bidirectional triode thyristor BCR1 via the first drive circuit. The bidirectional triode thyristor BCR2 is serially connected to an electrically heated strip, and then to the utility power AC input. The starting control unit is connected to a control end of the bidirectional triode thyristor BCR2 via the second drive circuit. The first drive circuit is interlocked with the second drive circuit.
