200 Watt Inverter Troubleshooting, step by step. it is TL494 based mini inverter for small appliances. it is 12 vdc operated and it provides 220VAC 50Hz, it is giving red light (fault) and its buzzer is ringing continuously. i shared the test points test and troubleshooting. i found that tl494 is damaged and its pin number 14 reference voltage are 11.19 volt. it must be 5.0 volt. when it is providing more voltage than its rated 5.0 volt. its internal reference regulator damaged. and its oscillator and related circuitry will not work.

I have a question that also raised after i just watched your other '3000 VA solar inverter series' . how do we know what mosfet is suitable replacement if we cant find the matching one. what is so specific in this circuit that we have to ensure that this mosfet is gona work, i mean if opt for a different mosfet what changes we need to do in this circuit ? i believe that the mosfet is driven by a transister at its gate so do we need a diffent transistor with different gain characteristics ? Can you show how the mosfet drive voltage affects the output ? Looking forward for more learning videos from you, Jazakallah. May Allah Subhana Wa Taaala give its reward to you.

Thank you Mr Hasseb. Regarding the 5V ref voltage, is it on pin 13 or 14 please?

@HaseebElectronics Жыл бұрын

pin number 14 is reference voltage. pin number 13 is output control

Nice trouble shooting...sir I want copy the program from microcontroller build induction stove, inverter, washing machine etc, Then copy in to another new one... because microcontroller is heart of appliances. Is it possible, if possible with development board.... please clarify with video... thanks in advance sir...

Will you try and repair this mini inverter?

@HaseebElectronics Жыл бұрын

sure if the repair cost is less than 65% of the equipment cost, we can repair it in this case TL494 SOP IC. it is around 1 dollar, if i can find locally, i will fix it
