Constant-frequency multi-resonant converter-fed DC motor drives [PDF]
, 1996 Low-inductance dc motors with high power density and low rotor inertia are becoming more attractive, particularly for servo applications. In order to maintain their current ripples within acceptable levels, power converters need to operate at high ...
