In this paper a high frequency series resonant dc link converter is utilized as a dc motor drive. This system generates a resonant current in a series link and switching is done at zero current instants, reducing switching losses to a minimal value. A Pulse Density Modulation (PDM) strategy, utilizing a current regulator loop and an external motor speed feedback loop, controls the resonant converter. A sinusoidal input fundamental current and nearly unity input power factor can be observed in different load conditions. The overall characteristics of the system, including such variables as maximum power, input current, start up, and transient responses are presented by digital simulation and verified on an actual prototype system.
