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...

This paper presents a cascaded H-bridge multilevel boost inverter for electric vehicle (EV) and hybrid EV (HEV) applications implemented without the use of inductors. Currently available power inverter systems for HEVs use a dc–dc boost converter to boost the battery voltage for a traditional three-phase inverter. The present HEV traction drive inverters have low power density, are expensive, a...

Fuel cells are considered to be one of the most promising sources of distributed energy because of their high efficiency, low environmental impact and scalability. Unfortunately, multiple complications exist in fuel cell operation. Fuel cells cannot accept current in the reverse direction, do not perform well with ripple current, have a low output voltage that varies with age and current, respo...

This paper presents a single-phase five-level photovoltaic (PV) inverter topology for grid-connected PV systems with a Sinusoidal Pulse Width-Modulated (SPWM) control scheme. The photo-voltaic arrays are connected to fivelevel multilevel inverter through the DC-DC boost converter. By implementing maximum power point tracking algorithm are producing more power from PV array. The DC power from th...

The paper presents a drive system consists of single-phase boost rectifier, space vector pulse width modulation (SVPWM) inverter, and three-phase induction motor. The single-phase boost rectifier is used to obtain near unity power factor and to reduce the harmonic distortion in the main supply. The SVPWM inverter is used to offer 15% increase in the output voltage and low output harmonic distor...

Abstract: This paper presents Simulation of three phase PWM Inverter fed Induction Motor Drive using Pspice. The proposed induction motor drive model employs only seven switches and incorporates an active current shaping feature. The boost converter at the input can give the required voltage at the input of inverter. The boost converter also improves the power factor. The drive works satisfacto...
