Design and Simulation of Integral Switching Cycle Control for Heating Resistive Load

Abstract

The Class of ac power controllers consists of Solid State Power Controller (SSPC) which connects and disconnects
the load to the supply according to the required power. Two important voltage control techniques are commonly used for
heating power control in ac power controller are Phase Control Switching (PCS) and Integral Cycle Control (ICC). In case
that PCS is used for resistive load, it can produce higher order harmonics and heavy inrush current while switching on in a
cold start. In ICC frequency contained is variable and smooth voltage control is not possible and output voltage control is not
continuous. To remove the disadvantage of both the method and have advantage of both methods author proposed new method
termed as Integral Switching Cycle Control(ISCC) for heating application. In this paper authors have reported design and
simulated results of ISCC method for heating application for resistive load along with the abilities and deficiencies of the
proposed method.
