Abstract
This power converter comprises a plurality of switching elements, an inductor, and a smoothing capacitor. An input current of low frequency from the AC source is intermitted by the switching element turned on and off at high frequency, and an output current to a load is restricted by the inductor. These switching elements are controlled in different patterns. While these patterns are repeated, a current is always supplied to the load and inductor. Therefore, the power converter can provide a desired output power, making the inductance required for the inductor into the minimum. That is, the power converter can combine miniaturization and high-efficiency.
