Abstract:
Renewable energies are exploited and it have been started to be used, many researchers have started to develop and designing inverter based the different topologies of power electronics devices such as BJT, GTO, MCT, SI IGBT and Thyristors. Most all of these inverters failed due inefficiency applied topologies used during inverter design which characterized by much power losses. In this research come with a design of a high solar power inverter based on SIC MOSFET use in order to reduce the system power losses and increasing efficiency of the System by applying SIC-MOSFET in topologies in inverter design.
The design of solar power inverter circuit has been performed using CAS100H12M1 1.2 kV SIC- MOSFET. The single-phase inverter circuit consisted of 4 SIC- MOSFET with LC filter and load, PWM block, PID controller to generate signal and then simulation have been performed using MATLAB/SIMULINK. However, the inverter had some losses in SIC- MOSFET and in diode. Therefore, this research presented calculations of those losses and total harmonic distortion (THD) where the inverter Efficiency have been increased up to 98% and total harmonic distortion (THD) with 5.01%. This research discussed the components used in designing and interpreted the simulation results.
