The parallel operation of several low-capacity inverters is better than a singular highcapacity inverter owing to the advantages of better extensibility and reliability. A simplified control method for parallel-connected inverters is proposed, which can balance the current distribution among the parallel-connected inverters with no interconnected communication lines. To verify the performance o...

circuit of the power supply in pulse width modulated (PWM) voltage inverters results in output voltage deviations. Although individually small, when accumulated over an operating cycle, the voltage deviations are sufficient to distort the applied PWM signal. This paper presents a new method to correct for the dead time deviations. The Pulse Based Compensator is less hardware and software intens...

This paper presents a new control technique to regulate the capacitor voltage in cascaded multilevel inverters. Without requiring transformers, the scheme proposed here allows the use of a single dc power source with the remaining n − 1 dc sources being capacitors. This paper focuses mainly to achieve an effective capacitor voltage regulation with the Phase shift modulation and energy storage u...

Multilevel inverters are a source of high power, often used in medium-voltage application. Multilevel converters have received increased interest recently due to high quality output waveform and decrease the harmonic distortion in the output waveform without decreasing the inverter power output. A multilevel inverter uses a series of semiconductor power converters, thus generating higher voltag...

Abstract – In this paper, a generalized power loss algorithm for multilevel neutral-point clamped (NPC) PWM inverters is presented, which is applicable to any level number of multilevel inverters. In the case of three-level inverters, the conduction loss depends on the MI (modulation index) and the PF (power factor), and the switching loss depends on a switching frequency, turn-on and turn-off ...
