摘要: The feasibility of achieving dynamic voltage restoration without the use injection transformer is investigated. configuration a proposed transformerless restorer (DVR) features separate energy storage capacitors for phase-to-phase isolation, cascaded switches/inverters boosting functions and replenishing charging circuit. Comparison scheme with conventional DVR conducted in terms regulation property, power losses, reliabilities, costs ride-through capabilities. seen to be advantageous over many aspects. Simulation results also demonstrate effective performance scheme.
