POWER CONVERTER AND METHOD FOR POWER CONVERSION

摘要

A power converter for controlling power flow between first and second voltages where a common connection links a first polarity of the first and second voltages, and a first electrode of a capacitance is coupled to the common connection. First and second switches are serially connected between the common connection and the second electrode of the capacitance. The second polarity of the first voltage is coupled through a first inductance to the connection between the first and second switches. Third and four switches are also serially connected between the common connection and the second electrode if the capacitance, but the second polarity of the second voltage is coupled through a second polarity of the second voltage is coupled through a second inductance to the connection between the third and fourth switches. A controller controls the switches in a variety of ways that determines the ratio between first second voltage.
