一种IGBT参数辨识方法、死区补偿方法及逆变装置制造方法及图纸

一种IGBT参数辨识方法、死区补偿方法及逆变装置，无需根据采样信号来判断电流方向，不会存在往复过零现象，避免了对于补偿效果的影响。同时不需要额外增加硬件检测板就能准确辨识出用于死区补偿的IGBT参数，避免硬件电路导致的延时情况。并且辨识出的IGBT参数同时包括死区时间和开关器件导通压降；且死区时间包括软件设置死区时间和IGBT导通、关断延迟时间，为软件设置死区时间与IGBT导通延迟时间的和，再减去IGBT关断延迟时间的差值，将辨识得到的死区时间和开关器件导通压降作为IGBT参数对逆变电路进行死区补偿，使得逆变电路的输出电压更接近理想输出电压，从而获得较好的输出性能。

A IGBT parameter identification method, dead time compensation method and inverter device

A IGBT parameter identification method, dead time compensation method and inverter device do not need to judge the direction of current based on sampled signals, and there is no reciprocal zero crossing phenomenon, which avoids the effect of compensation. At the same time, there is no need to add additional hardware detection board to identify the IGBT parameters for dead zone compensation and avoid the delay caused by the hardware circuit. The IGBT parameter and identified at the same time including dead time and switch pressure drop; and the dead time including software setting dead time and IGBT conduction, turn off delay time, set the dead time and the IGBT turn-on delay time and, for the software minus IGBT difference off delay time, voltage drop as IGBT the parameters of the inverter circuit for dead time compensation of dead time switching devices and guide the identified, so that the output voltage of inverter circuit is more close to the ideal output voltage, so as to obtain good output performance.
