Abstract: A system and method for a power inverter with controllable clamps comprises a first voltage swing path, the first voltage swing path including a first plurality of power transistors, the first voltage swing path producing portions of a positive half-wave of an output signal when active; a second voltage swing path, the second voltage swing path including a second plurality of power transistors, the second voltage swing path producing portions of a negative half-wave of the output signal when active; a first clamping component coupled to the first voltage swing path, the first clamping component forming a freewheeling path for the first voltage swing path, the first clamping component comprising a control terminal, the first clamping component having a first stored charge when the control terminal is in a first state and a second stored charge when the control terminal is in a second state, the first stored charge being greater than the second stored charge; and a second clamping component coupled to the second voltage swing path, the second clamping component forming a freewheeling path for the second voltage swing path, the second clamping component comprising a control terminal, the second clamping component having the first stored charge when the control terminal is in the first state and the second stored charge when the control terminal is in the second state.

Abstract: A method for controlling a first switch and a second switch is suggested, wherein each switch is an RC-IGBT and wherein both switches are arranged as a half-bridge circuit. The method includes: controlling the first switch in an IGBT-mode; controlling the second switch such that it becomes desaturated when being in a DIODE-mode; wherein controlling the second switch starts before and lasts at least as long as the first switch changes its IGBT-mode from blocking state to conducting state.
Abstract translation: 提出了一种用于控制第一开关和第二开关的方法，其中每个开关是RC-IGBT，并且其中两个开关被布置为半桥电路。 该方法包括：以IGBT模式控制第一开关; 控制第二开关使其在二极管模式时变得不饱和; 其中控制所述第二开关在所述第一开关将其IGBT模式从阻塞状态改变为导通状态至少等于并持续至少等于其长度。
