A topology for power conversion from single-phase to three-phase power line is proposed. The circuit is built on three basic passive elements: capacitance, inductance and transformer. It produces well-balanced three-phase network suitable for rural power application. Initial analysis is presented in order to validate the principle of operation. Theoretical analysis is supported by simulation and experimental...
When a three-phase power line connected to unbalanced loads, its terminal voltages and line currents become also unbalanced. The most unfavorable load for three phase network or stand-alone generator is a single-phase load. Present study suggests a novel method for operating single-phase load connected to three-phase network while keeping generator voltages and currents fully symmetrical. Theoretical,...
The paper presents an analysis of multilevel inverter, which comprised of cascaded 5-level Flying Capacitor (FC) cell and standard 3-level H-bridge cells. The advantages of the proposed inverter upon standard topologies are significant reduction of electrical components and as a result, lower size and weight. Moreover, the proposed inverter has simplified control algorithm due to the reduction of...
Time domain technique is used to analyze the LCC converter with capacitive output filter. The converter was operated with frequency control above resonance under heavy load conditions. The analysis is validated with PSPICE simulation and results from an experimental prototype.
The paper presents analysis of an ac-ac Frequency Converter using the method of Lagrange. Differential equation for the output current and its explicit solution in each time segment are derived. The theoretical predictions are validated by simulation and compared to the experimental results.
