In this article, a three-phase modular multilevel converter (MMC) with three-level neutral point clamped (NPC) sub-modules (SMs) along the placement of transformers in place arm inductors is proposed for PV grid integration. Compared to traditional MMCs, configuration reduces voltage and power rating switches requirement high capacitor bank. order analyze performance arrangement, we have implem...

In this paper a new sinusoidal PWM inverter suitable for use with power MOSFETs is described. . The output waveforms in the proposed PWM inverter are investigated both theoretically and experimentally. The fundamental component of the three-phase line-to-line voltage is increased by about 15 percent above than that of the conventional sine-wave inverter. The sinusoidal PWM switching scheme allo...

In this paper, a new coupled-inductor based modular multilevel cascaded inverter using phase-shift control is presented. The proposed can generate high output ac voltage standard low rating devices. number of levels in the pulse width modulation (PWM) and effective switching frequency filter are increased coupled inductors control. signals units phase-shifted by 360°/4n, where n units. r...

The Three Phase Voltage Source Inverter supplies invariably required variable voltage and frequency of the adjustable speed drive system. A number of pulse width modulation (PWM) schemes are used to obtain variable voltage and frequency supply from an inverter. The most widely used PWM scheme for a Three Phase Voltage Source Inverter is carrier based sinusoidal PWM and Space Vector Pulse Width ...

The switching magnet for beam distribution is served with Digital Signal Processor (DSP) controlled PWM switching-mode power supply (SMPS). This SMPS is employed phase-shifted parallel (PSP) operation of IGBTs. This technique allows ± 350 A, 2.5 Hz stair output, and ± 350 A at bipolar mode operation. Current feedback and input voltage feed-forward control schemes are applied to improve the outp...
