Optimal Design of Energy-Saving Induction Cooker Power Controller Based on Fuzzy Technology

Abstract:

Application of Soft-switching technique and fuzzy control is discussed to optimize traditional induction cooker controller. Soft-switching technique is used to improve output efficiency of induction cooker. Switch voltage regulation by fuzzy control are used to adjust output power of induction cooker. Soft-switching inverter consists of resonant DC link and LC resonant network. Resonant DC link is used to realize ZVS, and resonant network is used to eliminate harmonics. Fuzzy control based on look-up table is adopted to adjust duty cycle of switch mode regulated power supply, which changes the DC supply voltage, so that amplitude of AC signal inverted by induction cooker is changed to adjust output power of induction cooker according to the requirement, , ensuring the operating temperature aligned with the target temperature.
