Wireless Power Transfer Coil Switching Simulation for EMC Testing

The patent uses a simulation system that replicates the electromagnetic coupling conditions of dynamic wireless power transfer without requiring actual vehicle movement. The simulation apparatus copies the essential test conditions (coil positioning, power transmission, reception) in a controlled stationary environment, thereby achieving test accuracy while avoiding the complexity and cost of moving-vehicle tests

The patent introduces a simulation control unit as an intermediary between the test subject and the measurement system. This intermediary coordinates the positioning and operation of transmission and reception coils to replicate dynamic conditions, enabling accurate testing without direct vehicle movement and reducing overall system complexity

The patent replaces the mechanical system of actual vehicle movement with an electromagnetic simulation system. The simulation control unit electronically coordinates coil energization and positioning to replicate the conditions of vehicle movement, thereby maintaining test reliability while dramatically improving ease of operation by eliminating the need for physical vehicle movement

The patent performs preliminary setup and calibration of the simulation system before actual testing. The simulation control unit is pre-programmed with the switching patterns and timing for coil energization that correspond to different vehicle speeds and positions, allowing reliable testing to be conducted through simple operation of pre-defined test sequences
