This paper is related to a non-contact energy transfer system which can stabilize the load voltage with no-feedback control. A detachable transformer used in the system has a leakage inductance. Therefore load voltage decreases greatly in proportion to load current. A feedback control circuit of the non-contact energy transfer system is more complication than that of contact energy transfer system. Consequently even if without feedback control, a non-contact energy transfer system which can keep the approximate fixed load voltage is required. The authors analyze the load voltage characteristic in detail and researched the mechanism, and found a novel method which minimize the load voltage drop rate by using optimized capacitance value of two resonant circuits.
