of Tennessee, Knoxville, TN (United States). Air Force, Wright-Patterson AFB, OH (United States).Specific applications for bidirectional series resonant inverters include industrial motor controller, voltage regulator for hybrid-electric vehicle engine/generator, motor controller for aircraft actuators or electric vehicle propulsion, and inverter/rectifier for batteries and static Var controller. Bi-directional power control will be extremely important to a wide variety of areas including electric vehicles, utility power, aircraft power, and shipboard power. The topology is capable of boost-buck operation without a transformer. The proposed converter, because of its zero switching capability when built with advance switches like the MOS-controlled thyristor, can achieve efficiencies approaching 99%. The analysis will form the basis of a bi-directional series resonant converter design that can be fabricated and tested in the future. This paper will develop the circuit theory using Laplace transform techniques for a bidirectional series resonant converter with a shunt loaded inductor.
