Abstract:
1. An SR motor control apparatus, comprising: a first half-bridge circuit having an element array including two semiconductor switching elements connected in series at a connecting node, both ends of the element array being connected to a power source, and a neutral node of an SR motor being connected to the connecting node; a second half-bridge circuit having an element array including two semiconductor switching elements connected in series at a connecting node, both ends of the element array being connected to the power source, and a U-phase coil of the SR motor being connected to the connecting node; a third half-bridge circuit having an element array including two semiconductor switching elements connected in series at a connecting node, both ends of the element array being connected to the power source, and a V-phase coil of the SR motor being connected to the connecting node; a fourth half-bridge circuit having an element array including two semiconductor switching elements connected in series at a connecting node, both ends of the element array being connected to the power source, and a W-phase coil of the SR motor being connected to the connecting node; and a switching unit including at least two power modules on which the first to fourth half-bridge circuits are mounted.
