Algorithms of space-vector-based synchronized pulsewidth modulation (PWM) have been applied for control of dual-inverter fed open-end winding induction motor drives supplied by two isolated dc-sources with non-equal voltages. Results of modeling and simulation of these systems proved the fact, that techniques of synchronized PWM provide continuous phase voltage symmetry (quarter-wave symmetry, ...

This paper sets forth the reliability analysis of conventional isolated pulse width modulation DC-DC (IDC-DC) converters. The IDC-DC converters are categorized into single-switch (ISSDC-DC) or multiple-switch (IMSDC-DC) proposed framework encompasses analyzing impacts duty cycle, input voltage, output power, transformer turns ratio, components characteristics and time duration on overall perfor...

This paper presents a grid-connected system for renewable energy source (RES) applications. The proposed consists of modified switched-capacitor (SC) based multilevel inverter and DC-DC flyback converter. By using the converter voltages DC-link capacitors are adjusted to same values. SC-based has benefits like limited capacitor charging spike, reasonable size, power density, cost per output pow...

The multi-input dc/dc boost converter is proposed in this paper. The proposed converter uses two sources such as wind, photovoltaic(PV) and battery as a storage element for hybridizing alternative energy sources. This converter draws the power from two different sources depending upon climatic condition and deliver it to the dc load individually or simultaneously. The system is applicable for D...

Sjögren's syndrome is an autoimmune disease characterized by lymphocytic infiltration of the salivary glands. In the NOD mouse, a model for this disease, the development of lymphocytic infiltrates in the salivary glands is preceded by an accumulation of dendritic cells (DC). Given the key importance of DC in regulating the immune response, we characterized the DC isolated from NOD salivary glan...
