Role of power control system of high-frequency SRI using phase angle control technique for IOT based induction heating system

Abstract: In this paper, an efficient power control technique has been designed which is used to control the output RMS power of high-frequency full bridge series resonant inverter (HF-FBSRI) for induction heating application. A phase control technique is introduced in this work to control the dc link voltage. This controlled dc link voltage is applied to HF-FBSRI to control the RMS power of IH system. This intended control method assures a stable operation of whole IH system. To reduce the switching losses across switches, ZVS condition has been achieved, due to this, regulated heating effects occur. In this work, different RMS power is obtained at different phase angle and it is validated with Matlab/Simulink environment for IH system rated at 515W.
