发明名称 SINGLE-PHASE AC-DC CONVERTER
摘要 <p>There are included a diode bridge circuit (4) formed by connecting four diodes (4a - 4d); a shunt resistor (6) provided between the diode bridge circuit (4) and an N output; a semiconductor switching element (5a) connected in parallel with the shunt resistor (6) and one (4c) of diodes of a side to which the shunt resistor (6) is connected; and a semiconductor switching element (5b) connected in parallel with the shunt resistor (6) and the other (4d) of diodes of a side to which the shunt resistor (6) is connected. Current detection is conducted by using the shunt resistor (6) and semiconductor switching elements (5a, 5b) are controlled. As a result, the board size is reduced and the cost is reduced. &lt;IMAGE&gt;</p>
