The main purpose of this paper is to design a charge equalization circuit for series connected lead-acid batteries. The charger utilizes a three-level neutral point clamped (NPC) AC/DC converter with voltage balance control to charge the series connected rechargeable battery strings. This paper details the operation principles of the charge equalization circuit under different operation modes a...

Detailed analysis and parameter design for a resistorcapacitor-diode (RCD) clamped snubber used in the output rectifier of phase-shift full-bridge zero-voltage-switching (PS-FB-ZVS) converters are presented. Design equations and some properties of the clamped circuit are highlighted.

In all multilevel topology with several DC link, the voltage balancing problem of DC capacitors is a key problem. This paper proposes a new topology of chopper circuit for dc capacitor voltage balancing in diode clamped multilevel inverters (DCMLI). In the presented topology the number of switches is reduced respect to other proposed topology in literatures. Suggested topology is modular and ha...

This paper introduces a novel 7-level active neutral-point clamped (ANPC) switched capacitor multilevel inverter (SCMLI) with voltage-boosting capabilities. The proposed converter can produce seven levels and voltage boosting of 1.5 times single dc source. For the voltage, two self-balanced capacitors link neutral point are used nine switches. controlling output level-shifted modulation techniq...

An active clamped forward-flyback converter comprizing a current doubler scheme, which allows to boost the application range of MOSFETs for efficient rectification in low-voltage power supplies, is investigated first approximatively and second incl. commutations. Design equations and issues are given for the magnetical integration of filter inductors on the outer core legs of the transformer . ...

A circuit configuration, a circuit topological family, a buck-mode active clamped circuit, and an on the spot output voltage feedback management strategy of combined duplex buck–boost dc–dc chopper-mode electrical converter with highfrequency (HF) link (HFL) were projected and absolutely investigated during this paper. The steady principle characteristic and therefore the criterion for the key ...
