摘要： A swinging inductor is used to achieve zero-current switching in a resonant buck-type voltage converter. The swinging inductor exhibits the property of a relatively high inductance at zero current and low current, but it swings back to the original resonant inductance value at high current. In this way the high and medium regions of the current sine wave remain effectively unchanged. Upon circuit power application, the current rises slowly due to the high swinging inductance value, but this is an innocuous parasitic effect. Using the swinging inductance placed in series with a switching device to control the transfer of energy from the input source to the output load allows for a very efficient transfer of energy and it also prevents the current from becoming negative. Moreover, the efficiency level is sustainable over a wide range of input and output voltage requirements.
