A large electrolytic capacitor is always used to provide stable DC-link voltage in single-phase to three-phase power converter. However, the large electrolytic capacitor occupies a large volume and has a short lifetime as to the home appliances. And additional PFC circuit is needed to correct the grid current. In order to settle these issues, an electrolytic capacitor-less converter system is studied...
