Embodiment Construction
[0042] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation of the present application will be described in detail below by taking 3 IGBTs in series as an example and in conjunction with the accompanying drawings.
[0043] An example of an IGBT series experimental circuit embodiment involved in the present invention Figure 7 As shown, including the series IGBT group (1), the DC power supply U DC (5), freewheeling diode D (6), load inductance L (7), clamp unit (2), drive unit (3) and control unit (4). The control unit (4) is jointly implemented by an FPGA chip and a DSP chip, wherein the FPGA implements the function of a time extraction unit, and the DSP implements the functions of voltage equalization adjustment calculation and driving signal delay. The series IGBT group (1) is composed of three IGBTs connected in series, the first IGBT (IGBT 1 ) emitter E 1 with t...
