Title: Protection of inverter
Inventor: FURUHASHI TAKESHI
IPC: H02H7/122
Filed: 1986-09-05
Abstract: PURPOSE:To suppress surge voltage applied to a switching element, to be lower, by lowering an excess current detection level on the light load operation of an inverter. CONSTITUTION:When DC voltage VDC exceeds the set level VH of an amplifier 92, then output voltage is found at the amplifier 92, and the voltage is combined with the output voltage of a rectifier 93 and is directed to a level detector 94 for input. When the DC voltage is lower than the set level VH, then from the level detector 94, the output of 1 is generated when input voltage comes to voltage corresponding to a previously set excess current level, and the output of 0 is generated when the input voltage is lower than the level. Then the DC voltage exceeds the set level VH, then the output voltage of the amplifier 92 is added to the detection level of output current i0, and so by the level detector 94, excess current is detected on the level lower than the previously set excess current level.
