This paper presents the most important control theories for cascaded multilevel inverter based active power filters like, p-q theory with PI controller, average power method with carrier phase shifted pwm, instantaneous real-power theory with triangular-sampling current modulator, p-q theory with space vector modulation strategies for generating the switching signals for the operation. This paper also presents performance assessment among these control strategies.
