Abstract

In order to obtain a reduced harmonic content in the frequency domain and to enhance the fundamental output voltage, in this paper we use a control technique based on a Third Harmonic Injection PWM (THIPWM) reference wave, modulated by an Inverted Sine Carrier Pulse Width Modulation (ISCPWM) carrier signal. This technique was tested by Spice cat simulation, but also practically, by implementing it on the C8051F120 microcontroller, which controls the three-phase inverter bridge based on IRAMX16UP60A. The calculations volume per time unit is impressive, therefore, in the microcontroller implementation part, we made some approximations.
