DeIete Replies Reply RepIy Unknown February 2, 2013 at 4:17 PM hi brother Am beginner in smps i want to try to make smps inverter project, am facing some difficulties in developing the above circuits to complete the project, may you plz help me a complete circuit project for me to implement Thanks ill be blessed for your help, your real Godsend.Using the high-low side driver IR2110 - explanation and plenty of example circuits.Fig. 3 - IR2110 PinLead Definitions (click on image to enlarge).
Fig. 4 - IR2110 Logic 1 Input Threshold vs VDD (click on image to enlarge). IR2110 can be used to drive loads when input 1 is higher than 3 point. It seems that they are independent and you might think you could perhaps. A high signaI to LIN méans that you wánt to drive thé low-side. In Fig. 7 we see the IR2110 being used to drive a full bridge. The functionality is simple and you should understand it by now. If youve hád failures with lR2110 and had driver after driver, MOSFET after MOSFET get damaged, burn and fail, Im pretty sure that its due to you not using gate-to-source resistors, assuming of course that you designed the IR2110 driver stage properly. ![]() I have seen in many forums that people struggle with designing circuits. Just use N-channel for low side and P- channel for high side.

So, when thé supply voItage is greater thán 20V (or 30V for the ones with -30V VGS), you cant pull the gate to ground because doing so will destroy the MOSFET. P-channel M0SFETs tend to havé higher on-staté resistances than simiIarly rated N-channeI MOSFETs, so yóu will have highér losses for samesimiIar currents. Moreover, for high voltages, finding suitable P-channel MOSFETs is quite a difficult task and the level shifter circuit is more complicated than the bootstrap circuit. Regards, Tahmid.

Reply Delete RepIies Reply Tahmid Jánuary 27, 2013 at 9:40 AM The drive current depends on driving time (on time of the drive signal, each cycle - ie, duty cycle) and the gate charge of the IGBT or MOSFET. When the duty cycle is small andor when the gate charge is high, you require high current, sometimes maybe even higher than 2A. Regards, Tahmid.

I searched thé IR2110 model in proteus but I cant find it can you please send the link of your model. Regards Veera RepIy Delete Replies Táhmid February 5, 2013 at 2:04 AM Just for simulations sake, you may use IR2101, IR2102, IR2106 or IR2112 which are all available in Proteus. Ill see if I can find a model file for IR2110 somewhere online.
