Abstract :
In January, 1995 the Society of Automotive Engineers, Inc. (SAE) published a recommended practice for electric vehicle battery charging using inductive coupling (SAE J-1773) for use in the USA. This paper considers the case of a series-resonant power converter driving the coupling interface. The resultant topology, a four element series-parallel LLCC-type (SP-LLCC) resonant DC-DC power converter with capacitive output filter, is analyzed and the time-based modal equations are solved in steady-state by using a state-variable transformation. The analytical results are validated experimentally
