Design of Direct Power Controller for a High Power Neutral Point Clamped Converter Using Real Time Simulator
In this paper, a direct power control (DPC) strategies have been investigated in order to control a high power AC/DC converter with time variable load. This converter is composed of a three level three phase neutral point clamped (NPC) converter as rectifier and an H-bridge four quadrant current control converter. In the high power application, controller not only must adjust the desire outputs...
متن کاملModeling and Neutral-Point-Potential Control ofNeutral-Point-Clamped PWM Rectifiers using an Optimal Regulator
Modeling and Neutral-Point-Potential Control ofNeutral-Point-Clamped PWM Rectifiers using an Optimal Regulator Shoji Fukuda, Member, Yasumasa Matsumoto, Associate (Hokkaido University), Akira Sagawa, Member (Hitachi Co., Ltd.) Neutral-point-clamped voltage source rectifiers(NPCR) are suitable for high voltage systems because of their circuit structure. The NPCRs, however, have a problem that th...
متن کاملLoss 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...
متن کاملComparative Study of THD in 5-level Neutral Point Clamped Multilevel Converter Using Multicarrier PWM and SHEPWM Techniques
A multilevel inverter is a power electronic device made to synthesize a desired AC voltage from several levels of DC voltages. Some industrial drives require medium voltage and megawatt power level. For a medium voltage grid, it is troublesome to connect only one power semiconductor switch directly. A multilevel power converter structure has been introduced as an alternative in high power and m...
متن کاملDirect Torque Control for Three-Level Neutral Point Clamped Inverter-Fed Induction Motor Drive
Direct torque control (DTC) is a control technique in AC drive systems to obtain high performance torque control. The classical DTC drive contains a pair of hysteresis comparators and suffers from variable switching frequency and high torque ripple. These problems can be solved by using space vector depending on the reference torque and flux. In this paper the space vector modulation technique ...
