Title: Micro-controller control Algorithm for Low EMI Generation in Induction Heating System
Inventor: CJOI JONG MYEONG
IPC: H02M1/00
Filed: 2020-09-18
Abstract: The present invention relates to a method for controlling an induction heating device using a commercial AC power. According to fundamental principles of the induction heating device, in order to induce an eddy current in a cooking container, a large current having a high frequency suitable for a material of the cooking container has to flow through a working coil, so that a DC voltage obtained by rectifying AC 220 V applied to the working coil is switched by a power control semiconductor device (IGBT, SiC, MOSFET, etc.). Since a high DC voltage is switched at a high frequency, electromagnetic interference (EMI), which is unavoidable due to operating principles, occurs, and the electromagnetic interference (EMI) is conducted to other electronic devices through power lines or radiated into air, which causes failures to nearby electronic devices. While the conventional technology has solved the occurrence of the electromagnetic interference by using an AC filter, which is an expensive component, a PWM duty ratio of an MCU is changed to reduce generation of electromagnetic interference noise and lower a resonance voltage induced by the working coil, so that burnout of the power control semiconductor device caused by an overvoltage is prevented.
