A control circuit for a single-phase AC motor of a dryer, including an electronic starting circuit including a starting control unit, a first drive circuit, and a bidirectional triode thyristor; a second drive circuit; and a mechanical switch K is disclosed. The first drive circuit and the second drive circuit are interlocked with each other whereby enabling the mechanical switch K to be switched off as the bidirectional triode thyristor is conducting, and to be switched on as the bidirectional triode thyristor is cut off. The switching and drive control is implemented by way of controlling switch-on/off of the mechanical switch via electromagnet coil. |
