Abstract
Characteristics of the inverter circuit which LC filter has connected with each arm of a switching element of DC link is described. Switching component of an output voltage is reduced like the case which a filter has connected on the side of AC. But, LC filter on the side of DC shows effect sufficiently by a small capacity in comparison with the case which is connected on the side of AC of conventional inverter. It is because the voltage which is impressed on a filter is single polarity. As for controlled method, by making potential of control circuit coincide with potential of DC link, it becomes possible not to use expensive isolation amplifier and to detect an output voltage and a DC link voltage. By replacing a filter on the side of AC on the side of DC in this way, efficiency and accuracy of detection were improved.
