<p>An inverter apparatus having at least an inverting portion 4 for inverting a DC electric power into an AC electric power, wherein said inverting portion includes: high speed switching elements S1, S2...S6; driver circuits R1, R2...R6 for driving the high speed switching element; and a controller portion 5 for outputting logical driving ON/OFF signals for controlling the AC electric power to the driver circuit, wherein the controller portion controls so that the minimal time of the OFF signal of the logical driving ON/OFF signals for the high speed switching element comes to be equal or greater than a predetermined value, thereby protecting the high speed switching elements constructing the inverter apparatus from breakdown due to with such the short OFF pulse. <IMAGE></p> |
