摘要： A resonant inverter includes inductive elements (L1, L2) that allow the number of magnetic components in the inverter to be reduced. The elements (L1, L2) may be designed with a leakage inductance to eliminate the need for a large DC inductor. They may also perform the function of a current splitting transformer. The inverter switches may also be driven directly from the inverter circuit without a separate controller being required.

摘要： A resonant converter is provided which may be used for supplying power to the primary conductive path of an inductively coupled power transfer (ICPT) system. The converter includes a variable reactive element in the resonant circuit which may be controlled to vary the effective inductance or capacitance of the reactive element. The frequency of the converter is stabilised to a nominal value by sensing the frequency of the converter resonant circuit, comparing the sensed frequency with a nominal frequency and varying the effective inductance or capacitance of the variable reactive element to adjust the converter frequency toward the nominal frequency.
