Embodiment Construction
[0081] Below in conjunction with specific embodiment and accompanying drawing, the present invention will be further described:
[0082] Such as figure 1 As shown, the present invention provides a method for online estimation of the junction temperature of an IGBT power module, as follows image 3 The shown full-bridge inverter circuit is taken as an example to introduce the implementation process of this method in detail. The specific implementation steps are as follows:
[0083] Step 1. Build a full-bridge inverter circuit in Saber, V CE(ON) On-line measurement circuit, SPWM control circuit and gate-level drive circuit, V CE(ON) The two input terminals of the online measurement circuit are connected to the collector and emitter of the IGBT of the full-bridge inverter circuit to realize the connection between the full-bridge inverter circuit and V CE(ON) Connection of in-line measurement circuits such as figure 2 shown.
[0084] Step 1 in the embodiment specifically inc...
