Quasi-Z-Source Inverter with Enhanced Voltage Gain for Photovoltaic Power Generation
A quasi-Z-source inverter with a novel carrier based pulse width modulation (PWM) scheme is proposed for photovoltaic power generation systems. In this new technique, a high frequency sine wave is employed as carrier waveform instead of the conventional triangular wave in the simple boost technique. This increasess the shoot-through duty cycle for the given modulation index and hence the voltag...
متن کاملA Modified Series Z-Source Inverter Based on Switched Inductors with High Voltage Gain and Reduced Voltage Stress on Capacitors
In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...
متن کاملSingle-Phase Z-source Matrix Converter with High Voltage Gain
Abstract— This paper proposes a new type of converter called Single Phase Z-source Matrix Converter (SPZMC). The SPZMC is an ac-to-ac converter device. Simulated using diode bridge bidirectional switch cell. The simulation is performed in different loads with fixed input and variable output frequency. Pulse Width Modulation (PWM) switching strategy is used to obtain the variable frequency. The ...
متن کاملHybrid Z-Source DC-DC Converter with ZVZCS and Power Transformer Resetting: Design, Modeling, and Fabrication
This paper introduces a novel two transistors forward topology employing a z-source to achieve ZVZCS and power transformer resetting for various applications. Comparing with the forward converter, this topology has the advantage of displaying ZCS condition with an added Z-Source and no additional switches when the switches turn on, and that ZVS condition happens when the switches turn off. Duty...
متن کاملA New Structure of Buck-Boost Z-Source Converter Based on Z-H Converter
In this paper, a new structure for buck-boost Z-source converter based on Z-H topology is proposed. The proposed converter consists of two LC networks similar to the conventional Z-source and Z-H converters. One of the characteristics of the proposed structure is that, without any changing in its’ power circuit, it can be used in different conversions such as dc/dc, dc/ac and ac/ac. This unique...
