The outer diameter of the probe domestic PA50-F small four-jaw gold-plated needle is 0.68. The total length of the needle is 16

In the maintenance of the induction cooker, the IGBT power tube is often burned due to the measurement circuit, and it is necessary to make a small tool for preventing the IGBT tube from being burned. First make a 1:1 isolated power supply and then make an analog spool dummy load tool.


In the circuit, the transformers T1, T2, and T3 can be used with a 12V power transformer of about 30W, and the 2u capacitor can be used in a scrap induction cooker. The diode uses an ordinary light-emitting tube.


During the overhaul, the analog dummy load is connected to the output of the main board to replace the reel. Turn on the power If the circuit is not faulty, the four LEDs in the standby state are not bright. After pressing the power button, the four LEDs are flashed according to a certain frequency (different models, different frequencies, probe signal frequency); If the LED is always on or off, it indicates that the circuit is faulty. Never connect the mains directly before troubleshooting. Otherwise, the IGBT tube and bridge stack fuses will be damaged. When you are skilled, you can judge the working state of the circuit according to the brightness and frequency of the flashing of the LED.
