How to repair a dead induction cooker , step by step procedure explained

-
Hello friends,
Welcome to Electronics Tube 
In this blog I will be sharing some information on troubleshooting of induction cookers. Nowadays there are variety of brands manufacturing different types of induction cooker. However the topology of the main circuit is common in all induction.

An induction cooker transfers electrical energy by induction through the induction coil into vessel made up of ferromagnetic material . It consists of a induction coil that is driven through an IGBT ( Insulated Gate Bipolar Junction Transistors) which is further driven by a logic pcb board that consists of a microprocessor or any microcontroller depending upon the design. The IGBT imparts power in the induction coil that creates electromagnetic waves. This electromagnetic wave is used for heating effect to use in cooking. There is a temperature sensor mounted on the top of the induction coil that detects the temperature and sends signal to the logic board about the temperature conditions. Through the control panel of induction  we can adjust the temprature, time, mode, etc. These all the tasks are performed by the microprocessors or the microcontroller embedded in the circuit design.

There are a lot of problems seen in the induction cooker when it's used for a long duration of period.
Here I am providing few steps for troubleshooting a dead induction cooker.

How to Repair Induction Cooker ?

Equipment required :
1. Screw driver
2. Soldering Iron
3. Digital Multimeter

Step 1. Check the power cable via continuity test using multimeter.

Step 2. Check the Fuse on the PCB board.

Step 3. Check the IGBT and the bridge rectifier module using the digital multimeter.

Step 4. Check the non-polar capacitors mounted on the board.

Step 5. Check the microprocessor or microcontroller unit on the pcb board.
However there is very less chance that these would be damaged.
More than 80% of the problem is resolved in following Step 1 to Step 3.

What to do if IGBT is damaged ?
If the IGBT is damaged replace it with a new one with same part no.
Many of the induction have "H20R1203" IGBT in their models.
If a faulty IGBT is found do not forget to check other discrete components around it. Because sometimes the failure of IGBT causes damage to the nearby Diodes or other components in its path.
While replacing the IGBT use thermal grease for better heat dissipation.

Hello friends, In this blog we will be discussing about some famous audio power transistors that can be found easily online or at any nearby store. If you are designing a power audio amplifier it is very important to choose the best power transistors for the output stage. There are varieties of Power transistors available around the market. But before choosing the power transistors for the power amplifiers one must know about the necessary specs for design such as wattage , power supply range, current handling capacity, etc. Here below I am providing the  List of top Power Transistors  that are being widely used in high power amplifiers. LIST OF COMPLEMENTARY POWER TRANSISTORS : #1. TIP 3055 NPN and TIP 2955 PNP Complementary Pair Transistors   These transistors are widely used in old design class AB-type amplifiers. The maximum power dissipation of the Transistor is 90-Watts. It as well comes in metal case packing and it's power dissipation is 120-Watts. The other package i

Hello   friends,  Welcome to   Electronics Tube India .   Today in this blog we will be sharing you an amazing power amplifier circuit that is capable of driving two 12-inch woofer or speakers. The maximum power output of this amplifier circuit is 50-Watts per channel. This is stereo power amplifier circuit so total output power of the circuit is 100-Watts (if the input transformer rating is 24 volts capable of delivering 6 amps of current). This is a single supply power amplifier so it does not employ any dual power supplies, hence reduces the cost of building. The circuit is built around famous audio amplifier chip  TDA2030  and pairs of   MJE3055 (NPN-75Watt)  and  MJE2955(PNP-75Watt) .The pair of mentioned transistors are added at the output stage of TDA-2030 to increase the output of amplifier. The use of TDA2030 audio amplifier chip provides Hi-Fi sound quality. The stability of this amplifier is very good. The audio chip along with the power transistors should be mounted

Hello  Friends,    Welcome to  Electronics Tube  Today in this blog I will be discussing about "How to make 4.1 Amplifier System at home. I am providing the details for the circuit and assembling of the amplifier here. Please read the blog carefully. If there is any issue please comment below : About the Circuit Diagram for 4.1 Channel Amplifer The circuit discussed in this blog is based on a class AB-Type Amplifier and is powered using single supply. The total output power of the circuit is near about *100-Watts. For satellite speakers the output power for each channel is about 10-12 Watts. The satellite speakers could be a woofer speaker (Tweeter connected in parallel) having impedance of 4-ohm and power up to 20 Watts  (4" to 6"). If needed a tone control circuit can be introduced for satellite stage speaker to control the high stage bandwidth (Bass and treble). For satellite speaker I am using a  an 4 different amplifier stages build around the popular TDA 203
