| titleOfInvention | The passive protection circuit of IGBT |
| abstract | The present invention relates to the passive protection circuits of IGBT, belong to applied power source field.The driving signal of present invention driving circuit makees power supply, including reference voltage circuit, Vce sample circuit, protection circuit；Reference voltage circuit includes the BE knot of resistance, voltage-stabiliser tube, triode, electrical connection are as follows: driving signal anode-resistance-voltage-stabiliser tube anode-regulator tube negative-triode BE knot-driving signal；Vce sample circuit includes diode and voltage-stabiliser tube, electrical connection are as follows: the anode of voltage-stabiliser tube in the pole C-diode cathode-diode cathode-voltage-stabiliser tube cathode-voltage-stabiliser tube anode-reference voltage circuit of IGBT；Protecting circuit includes resistance and N-type triode, and resistance is the ESD protective loop of triode.The present invention does not increase external auxiliary power supply, and the biggish PWM of duty ratio is cut into the lesser square-wave signal of duty ratio, and only IGBT works long hours in high current saturation state, reduces the operating current of IGBT under the premise of non-stop-machine, guarantees IGBT safety. |
