Abstract

An inverter includes first, second, and third dc voltage sources, first and second switching elements which are connected in series to the first dc voltage source, a signal generator section for producing first and second control signals on the basis of the output voltage from the third dc voltage source, first and second signal level converter sections for converting voltage levels of the first and second control signals based on the output voltage from the second dc voltage source and thereby respectively generating first and second output signals, and first and second driver sections responsive to the first and second output signals for supplying the first and second switching element with first and second driving signals on the basis of the output voltage from the second dc voltage source and thereby respectively turning the first and second switching elements on or off. At least either one of the first and second signal level converter sections includes a turn-off section responsive when at least either one of the output voltages respectively from the second and third dc voltage sources is lower than a predetermined voltage level for turning the first or second switching eleme…
