In a method of operating an inductive device, for example a reluctance motor having a winding L2A, a controlled switching circuit connected to the winding is repetitively configured in successive configurations. In a first configuration, a source of electrical energy V1 is electrically coupled to the winding L2A, by turning transistor Q2A on, to establish a magnetic field in the winding. In a second configuration, a capacitor C2A is electrically coupled to the winding, by turning transistor Q1A on, to discharge the capacitor into the winding to maintain or augment the magnetic field established in the winding during the previous configuration of the switching circuit in the first configuration. In a third configuration, the capacitor C2A is electrically coupled to the winding through diodes D3A and D4A, by turning off transistors Q1A and Q2A, to charge the capacitor by a current induced in the winding by collapse of the magnetic field in the winding. |
