| 摘要 |
The present invention relates to a DC to AC inverter comprising a plurality of voltage controlled switching devices, where one or more of the voltage controlled switching devices is driven by a drive circuit comprising: a bridge switching circuit (59), a transformer (28) with a primary winding (29) and a secondary-winding (30), a transition selection circuit (60) coupled to a control terminal of a respective voltage controlled switching device (40) of the inverter, at least one inductance (37) that forms at least one resonant circuit with the input capacitance (41) of the control terminal, wherein the bridge switching circuit (59) can be operated to generate drive pulses via the selection circuit (60) to operate the respective voltage controlled switching device (40). |
