Optimization of operating parameters in a unipolar PWM inverter

The increase use of renewable dc or battery as a source has further emphasized the importance in efficient design of inverter. This paper discusses a study to determine optimum operating parameters of a commonly used pwm unipolar inverter. Variations on the input voltage level and switching frequency will be investigated to see their impacts on the operation of the inverter as well as harmonics produced. Results through modeling and calculations demonstrate that meticulous selections of design parameters yield inverter´s operation with the highest efficiency at the lowest level of output distortions.
