Title: Single phase inverter circuit
Inventor: YOSHIKAWA YOSHIROU
IPC: H02M7/5387
Filed: 1984-05-18
Abstract: PURPOSE:To simplify a circuit by controlling ON-OFF of the first to fourth transistors by a switching signal from a comparator. CONSTITUTION:A current is flowed in a direction through terminals S and P to a rotor winding 3, and a rotor 2 maintains counterclockwise rotation by the polarity of the stator core 1 and the rotary inertia of the rotor 2. Then, the output of a comparator 12 is sequentially switched in response to the rotating angle of the rotor 2, the ON-OFF state of the first to fourth transistors 8-11 are simultaneously switched to switch the current flowing direction to a stator core 3. Accordingly, the continuous rotation of the rotor 2 is maintained by the polarity of the core 1 and the inertial rotation of the rotor 2. Thus, a particular conventional switching controller is not necessarily provided to simplify the circuit.
