| Abstract: | This paper examines a noncontact 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 noncontact energy transfer system is more complicated than that of the contact energy transfer system. Consequently, even if without feedback control, a noncontact energy transfer system which can maintain the approximate fixed load voltage is required. The authors have analyzed the load voltage characteristic in detail and researched the mechanism, and found a novel method which minimizes the load voltage drop rate by using optimized capacitance value of two resonant circuits. © 2005 Wiley Periodicals, Inc.
