This paper explores Switched Inductor (SL) Zsource inverter which adjusts the voltage and have application in Fuel cells (FCs) which have achieved global attention as an alternative power source for hybrid electric vehicles (HEVs). The proposed inverter uses inductor and capacitor circuit to join the source and load circuit. On comparing with the initial Z-source inverter, the explored circuit ...

The maximum boost control method for a single-phase switched-boost inverter (SBI) and single-phase Z-source inverter (ZSI) is proposed in this paper. In the proposed method, the low frequency voltage is added to the constant voltage for generating the variable shoot-through time intervals. For improving the AC output quality of the inverter, an active power switch is used to replace one of the ...

This paper presents a soft-switching DC-DC boost converter, which can be utilized in renewable energy systems such as photovoltaic array, and wind turbine connections to infinite bus of a big power network, using grid connected inverters. In the proposed topology for the DC-DC boost converter, the main and the auxiliary power switches are turned on and turned off with zero voltage switching (ZV...

A new modulation strategy has been introduced in this paper order to enhance the boost factor for three-level quasi-switched T-type inverter (3L-qSBT2I). Under approach, component rating of power devices is significantly decreased. Moreover, use a larger produces smaller shoot-through current. This benefit leads reducing conduction loss significantly. Furthermore, neutral voltage unbalance also...

The main objective of this project to control the common mode leakage current by using virtual dc bus with PV systems. The power which we receive form the PV panel is not a constant supply due to various condition. In order to overcome this issue we are using Buck Boost converter for generating constant voltage supply to the inverter. The negative pole of the dc bus is connected directly to the...

This paper presents a carrier modulation technique to control the three-phase, two-level quasi switched boost inverter. PWM algorithm uses three waves, first of which is for inverter while others are booster. The factor depends on short circuit interval DC/DC booster and When DC twice that inverter, index can be enlarged. new analyzed, calculated, simulated, tested. analysis calculation results...

Renewable energy resources are gaining popularity now a days. Their input varies with changes in climatic conditions. So the output from them is not a constant value. The output of the energy sources have to be connected to grid. But the grid voltage is always constant. So the output from the renewable energy converters have to be constant. But the input of the renewable energy converters alway...
