SIMULATION OF SOLAR BASED INDUCTION HEATING SYSTEM

Abstract

Induction heating system use electricity for the generation of heat, where solar energy is
largely available energy for generation of heat. Combining solar energy with induction heat generation
technique is the efficient solution for the heat generation application. Resonant converters featuring soft
switching are commonly used in domestic induction heating applications due to their high efficiency and high
power density. The design and implementation procedure of an improved efficiency and low profile resonant
inverter for induction heating applications is presented. By using automotive-grade MOSFET devices, reducing
conduction losses against the classical IGBT-based converter. In addition to this, the reduced switching times of
MOSFET devices decrease switching losses, further increasing the conversion efficiency. The proposed system
presents an effective control scheme incorporated in class E resonance induction heating by using solar energy.
Pulse width modulation technology is used for charging the battery from photovoltaic array. The principle of
induction cooker is based on heating the metallic pan with circulating eddy currents induced by high frequency
AC magnetic field. The coil within the induction cooker and the load (pan / pot) acts as a transformer if the load
has an electrically conducting base. If the conducting base is ferromagnetic, then the power is transferred with
high efficiency.
