Abstract
Inverter, is an electronic device or circuitry that changes direct
current (DC) to alternating current (AC). The output voltage and frequency of
the inverter can be changed. There are different modulation methods used in
inverter control. Some of these methods can be applied digitally, some
analogously. Classical Sinusoidal Pulse Width Modulation (SPWM) is a method
normally performed analogously. Known methods for digitally applying this
method are regular sampled sinusoidal PWM methods. In this study, the
implementation of symmetric regular sampled sinusoidal PWM method is discussed.
Two fundamental factors that are effective in this kind of modulation methods
are investigated by harmonic analysis of switching frequency and modulation
index, inverter pole voltage and line voltage. From an inverter that supplies a
three-phase RL load, the fundamental component and the generated harmonics are
investigated using the Symmetric Regular Sampled SPWM method with five
different switching frequencies and three different modulation index values.
Modulation index is investigated for linear region and over modulation regions.
Low, normal and high switching frequency samples are also chosen for switching
frequency. The obtained harmonic analysis results are presented in the study.
