2017年1月21日 · I need to include a short circuit protection for my new smps for amplifier using an IR2153 driving a couple of IRF740 in half bridge. Input voltage is 230vac. output voltage 40-0-40. Transformer is an ETD 39. Power around 500-600 watts. I already winded a small 15mm core for this purpose and the ratio is 80:1 bifilar.

2020年2月4日 · the IR2153 doesn't have any pin for feedback for voltage regulation. is it possible to add a feedback circuit to this smps based on IR2153?

2016年3月20日 · Need some moderator to change my thread's title to -> "IR2153 + regulation and protection but need help calculating the values" :bsdetector:----look at my current setup but this was before i soldered the opto + 220 ohm + 2k2 + TL431 and the 2V out .. also im using gate stoppers unlike in the sch.

2016年3月5日 · Im making a half bridge 300v 14khz square wave power supply by using two ultra fast IGBTs and a IR2153 gate driver,when the power part of the circuit is inacvtive(Vcc=0 V) the gate-emitter waveform on high side IGBT is good with peak to peak voltage of VGE=11200mV , but when the power is activated and no load is at the output of the circuit(IC=0) the waveform will contain high frequency noise ...

2010年12月2日 · As a first step to build a Half Bridge , I assembled one with IR2153 and an ATX transformer. with the frequency set to 40khz (RT - 18k , CT - 1nf) , it was outputting around 26 Volts 2 mosfets - 4n60 (FQPxx... 2.6 amp 600v). initially I had two Bulk caps 100uf/250 volts. I connected the output to load, over 1 amp and all seemed okay.

2013年8月25日 · The problem with IR2153 doesn't suggest shoot-through problems, because the driver has sufficient built-in deadtime. A possible problem is exceeding diode commutation dv/dt with inductive loads. In this case, increased gate resistors or preferably fast-off/slow-on RD combinations can help. Or using modern MOSFETs with fast reverse diode.

2008年1月22日 · one more thing,i used 1n4148 diode.will it be fine or use other one? 1N4148 where? We never saw a complete schematic yet.

2009年6月23日 · ir2153 problem It looks like a simple decoupling / reservoir capacitor. Thr cap has to have enough "hang time" to supply VCC during periods where the "rectified AC line" is in the valley, below whatrver voltage the internal shunt regulator clips it at against RVCC (or where Vline/RVCC is less than VCC current at regulation point).
