Simulation of Induction Cookers System Using Resonant Converter Circuit With the Aim of Optimizing Efficiency
Abstract:   (627 Views)
It’s known that equalizing inductive reactance (caused by winding inductance) with capacitive reactance (caused by resonance capacitor) and creating resonant frequency is imperative to produce heat in metal pan located on induction cookers’ coil fed by classic resonant convertor.
Moreover, the magnetic field induced by the currency passing through the induction cooker coil (with an active component and high frequency), produces Eddy currents in the pan and the Ohmic losses resulted from these currents (Req×I2) causes heat in the pan.
Thus, in order to produce higher heat and cook faster, there is a need to increase the transitional active power to the cookers’ coils of these types and this in turn, raises the system efficiency.
Increasing the transitional active power to the induction cookers’ coil means increasing the Ohmic losses caused by Eddy currents produced in the pan. To achieve this, by changing the circuit structure in classic resonant converter (using a voltage amplifying inductor in the converter input) as well as changing the switching system, a converter named “proposal converter” is developed and studied in this dissertation. This proposal converter increases the system efficiency by about 20 percent.
Keywords: resonant converter, induction cooker, efficiency, active power, switching
