· One more output level, less ripple current content
· Output PWM waveform is more similar to sinusoidal wave, better harmonic compensation effect
· The volume of LCL filter is reduced, beneficial for AHF module design
· Less inductance loss, improving the system efficiency
· IGBT withstand voltage stress cut into half, effectively reduce the switching loss
· Less switching loss of IGBTs, more thermal margin, higher switching frequency
