Hi Haseeb and thank you so much for all your excellent videos! I have learned so much from all your SMPS videos and now about refrigerator inverter boards. When you have some time, would you consider doing a video on refrigerator main control circuit boards? I’m having some problems with mine and would like to understand more about how it operates. Thanks again so much and take care!

Thankyou for the tutorial. I learnt that the input voltage to the VCC is 230V. I also learnt that the control votage is 3V. In a good VCC what is the voltage at each connection to the compressor?

[@rogerschelling5668]

Hi. Thanks for your videos. Is there a practical method to convert the VCC3/220VAC to operate with 120VAC? TIA

[@HaseebElectronics]

if the board have 2 capacitors, then you can use that central pins of capacitor can be grounded but some boards have voltage sensing line, which gives the voltage sensing a voltage divider network. in that case you have to redesign that voltage divider network to give voltage value to microcontroller

[@rogerschelling3162]

@@HaseebElectronics Oh I think I see the "voltage sense line" is sensing the voltage of the bulk capacitor and connected to microcontroller ADCIN0. ? R115(620K), R116(620K),R117(620K),R103(12K) are the divider?

[@HaseebElectronics]

​@@rogerschelling3162 yes there is special line to check the dc voltage to adjust frequency and voltage

[@rogerschelling3162]

@@HaseebElectronics If I am looking at the right divider resistors R115,R116,R117,R103 then interesting - they are the same value on the 220VAC(2456) inverter as the 110VAC(1156) inverter. The 110VAC(1156) has 2 capacitors 820uF/200V. The 220VAC(2456) has 1 capacitor 400V/220uF.

[@HaseebElectronics]

wonderful. done boards have this vsense pin voltage divider different than 220 now you can modify it easily if the 400v/220 if have connection points on the board for another capacitor then install another 200 volt capacitor and take the central common point of capacitors to the bridge input line and modify the input circuit as the 110 volt board

[@martinmonaliza5597]

Hello. Please tell me the specifications of this diode. No matter what I tried, I did not get results. zd is written on the board, which should be a zener diode. The part number on the diode is 5AY. This diode is related to the inverter board of the refrigerator compressor. Thanks

How to this pcb run with out compressor .i think this type PCB to run must wont compressor feed back voltage for run micro control

[@HaseebElectronics]

you are right. it starts and waits for the feedback through its sense lines which are connected to UVW lines through resistors if compressor is not connected, that time the MCU disconnects the drive in few seconds

[@didingelectronics4846]

my friend the igbt module maybe there are shorted diode inside thats why the output voltage drop..u can hang the output signal to ipm

[@HaseebElectronics]

you are right. if the protection diode is short internally then at full 3 phase operation the load arrives at main capacitor so tge DC rail fuse blows up in that case. and the echo signal to the microcontroller is hang. so the microcontroller cannot generate the next stepping pulse

Hi there.....i hope you can help me out to save some money. I live in Europe. I have a siemens inverter refrigerator. 2 months before it stops working and the motor does a like week 'bzzzzz' sound. I am amateur in this things but i have a hakko soldering iron and a fluke 179 multimeter and i know/have a little practice about soldering/desoldering. I have test all the 33uf electrolytic capacitors. 3 of the capacitors have regular values, +/-5%. One of them have if i remember right is 584 uf and the other about 48uf. I changed the 2 "faulty" capacitors and voila....nothing happended.....same as before. The reading of the new capacitors are equal with the old original ones that i repleace (high- 584-48uf). I notice that when i measure these 2 capacitors soldered in the board values are high, but when i dessolder it and test it again off the board the values are correct. Also the 2 'old' original capacitors that i took off the board have the right values 31.8/32.5 uf. I don't know what to do, should i replace and the other 33uf capacitors or no? Please help me my friend!
