A voltage source inverter with variable frequency and variable voltage is applied for three-phase interior permanent magnet synchronous motor (IPMSM) drive for variable speed application. To obtain the required output voltage in the line side of the inverter a suitable pulse width modulation technique is used. The most prominent PWM techniques are Sinusoidal pulse width modulation (SPWM) and Space...
This paper presents the compensation principle using PI and ANN control strategies of the USSC in detail. The USSC is an active filter (AF) and it compensates the reactive power, harmonics in both the voltage and current caused by loads. The USSC makes use of two back to back connected IGBT based voltage source inverters (VSIs) with a common DC bus. One inverter is connected in series and the other...
