Loss Balancing in Three-level Active-neutral-point-clamped Converter

The 3L-NPC (Neutral-Point-Clamped) is the most popular multilevel converter used in high-power medium-voltage applications. An important disadvantage of this structure is the unequal distribution of losses among the switches. The performances of 3L-NPC structure were improved by developing the 3L-ANPC (Active-NPC) converter which has more degrees of freedom. In this paper the switching states a...

A new control method for the three level active neutral point clamped converter for low speed applications

This paper presents a new control method for the Three-level Active Neutral Point Clamped (ANPC) converter. The advantages of this method are presented and a power loss analysis is made for an extreme modulation index. The results obtained are compared whit those obtained for two other control methods. Simulation and experimental results are presented in order to validate the theoretical studie...

Zero-voltage switching for the neutral-point-clamped (NPC) inverter

This paper proposes a transformer-assisted pulsewidth-modulation zero-voltage-switching neutral-pointclamped (NPC) inverter. With the assistance of a transformer-assisted small-rating lossless auxiliary circuit, the main switches work with zero-voltage switching without suffering from any voltage/current spikes, under simple explicit control. The technique allows for higher operating frequency ...

Active Filter-Based Hybrid On-Chip DC-DC Converter for Point-of-Load Voltage Regulation

An active filter-based on-chip DC–DC voltage converter for application to distributed on-chip power supplies in multivoltage systems is described in this paper. No inductor or output capacitor is required in the proposed converter. The area of the voltage converter is therefore significantly less than that of a conventional low-dropout (LDO) regulator. Hence, the proposed circuit is appropriate...

Smooth Switching Technique for Voltage Balance Management Based on Three-Level Neutral Point Clamped Cascaded Rectifier

Abstract: This paper discussed the topology of in the three-level neutral point clamped cascaded rectifier (3LNPC-CR) for designing the Chinese Power Electronic Traction Transformer (PETT). To balance the DC-link voltage (Vdc) in 3LNPC-CR, a smooth switching technique is proposed in this paper. The controlling processes of each module are relatively independent when the proposed technique is ap...
