This paper presents a three-level hybrid active power filter (HAPF) combined with Quasi-Resonant DC-Link (QRDCL) soft-switching circuits in a three-phase four-wire system. Hybrid active power filter is a combined system of passive filter and active power filter, so it can compensate system harmonic current, reactive power and neutral current with a low dc voltage. Quasi-resonant dc-link circuits use...
This paper presents a combination of a quasiresonant dc-link (QRDCL) inverter and a generalized three-level inverter. QRDCL inverter can decrease the dc-link voltage to zero in order to provide a zero voltage condition for the power devices. The voltage stresses of the power devices can be released and the switching losses of the inverter can be reduced under zero-voltage switching (ZVS). Generalized...
This paper presents a three-level three-phase four-wire active power filter with a quasi-resonant dc-link (QRDCL) soft-switching auxiliary circuit. The three-level quasi-resonant dc-link circuit is constructed by two symmetrical two-level quasi-resonant dc-link snubbers and each snubber can be operated independently. Its operating principle is presented in this paper. Additionally, a direct pulse...
