Patent ID: 7902787

Claim:
A driving circuit for a single-phase switched reluctance motor, the driving circuit comprising: a switched reluctance motor; a voltage source which supplies energy to the switched reluctance motor; and an inverter circuit which is connected to the switched reluctance motor in parallel so as to temporarily store energy of the voltage source, and then supply the energy to the switched reluctance motor, wherein the inverter circuit comprises: a capacitor which is connected to the switched reluctance motor; a first node which is arranged between a first side of the switched reluctance motor and the capacitor; a second node which is arranged between a second side of the switched reluctance motor and the capacitor; a discharge switch which is connected between the first node and the capacitor; a first phase switch, a phase winding, and a second switch which are arranged between the first node and the second node; a third node which is arranged between the discharge switch and the capacitor; a fourth node which is arranged between the first phase switch and the phase winding; a fifth node which is arranged between the phase winding and the second phase switch; a first diode which is connected to the discharge switch in parallel; a second diode which is connected between the third node and the fifth node; and a third diode which is connected between the fifth node and the fourth node.
