Surge voltage suppressed power inverter using a voltage driven switching circuit |
摘要 |
A power inverter using a voltage driven switching element, capable of suppressing an excessive surge voltage which is generated on high-speed switching of IGBTs or MOSFETs, and suppressing radio frequency oscillation after the suppression of the surge voltage. The power inverter includes a switching element rendering a power path conducting and non-conducting, and a speeding-up circuit (17, 18) of a feedback path in an active clamping circuit added to the switching element. <IMAGE> |
