I am new to electronics So I need help to understand the working of the induction cooker circuit. I searched on the google but could not find the simple answer. Below is the attached circuit commonly found in home based induction stoves but it seems to be totally different from the theoratical circuit on the internet. In this circuit, as per my understanding, the ac supply is passed to rectifier that converts it to pulsating DC C2 capacitor is used to smooth the voltage and then this voltage is injected to the mosfet where low voltage signal can be used to control the mosfet(switch). If the switch is on then the induction coil starts. So its all the process is to convert AC to DC and then using the switch to on off the circuit.
My quetions are.
- What are the purpose of capcitor C1 and C3 and inductor L1 in this circuit?
- Does the induction cooker main coil is operated on DC Voltage?
- Why the fuse blows when I directly provide the AC voltage to Main induction coil L2. Shouldn't Magnectic field arround the coil provide some resistance for the current flowing through it.
If I am getting something wrong, please correct me. Would be greatful for any help. Thanks in advance.
