Abstract：With simple SPWM strategy, the capacitor voltage ripple of Z-source inverters keeps constant. However, the voltage ripple is related to the phase angle of reference vector under SVPWM, so its derivation is complex. It is considered if the inductance of Z-source is large the capacitor voltage ripple is traditionally independent of the inductance, while if it is small, the capacitor voltage is related to the inductance. The critical inductance and capacitor voltage ripple are also derived in this paper. Simulations and experimental results have verified these theoretical findings.
