The concept of replacing mechanical switcher using Solid State Devices (SSR) as the medium of relaying high power AC load has already been recommended five decades ago using Dual Thyristor or Triac. The rapid growth in SSR field has now resulted in using dual IGBTs, dual JFETs, dual MOSFETs or dual HEMTs semiconductor devices to control high powered AC loads. One of the drawbacks of all the systems above is that they all using two semiconductor devices to operate for both half cycle of the single phase AC waveform, with either anti-parallel or anti series-arrangement incorporated. We have modeled a novel SSR, using only one MOSFET semiconductor device with a new SSR module packaging. This novel Uni-MOSFET SSR is capable of operating on both half cycles of an AC waveform and eliminating problems associated with dual semiconductor SSR system. Moreover, in this paper we have explained the simulations proving that the Uni-MOSFET SSR is able to control resistive load and able to compensate capacitive and inductive as a SVC, which is as good as its predecessor the Dual-Thyristor SSR. The draw back would be the complexity of the control signals of the Uni-MOSFET SSR for TCR but we have managed to simplify using equations. Our novel SSR is cost efficient, low noise and works well as a load switcher, circuit breaker or compensation switch for single phase electrical network system.
