To provide transmission-line voltage support, a static compensator (STATCOM) offers the optimal solution in terms of price, reliability, and dynamic performance. Simpler layout for switches, reduced component count and smaller dc-link capacitor values are the attractive features of the proposed topology over the diode clamped and cascaded multilevel converter. Two dc-link voltage sources with v...

This paper presents a micro controller based control of multilevel inverter for single phase Induction motor. IGBT is used as power element. Pulse width modulation techniques (PWM), introduced three decades ago, are the most used methods to control the voltage and frequency supplied to electrical AC machines. This work proposes a new switching scheme for the cascaded H-Bridge multilevel inverte...

conclusions treating obesity, increasing physical activity and quality of married life are proposed as practical solutions to reduce bp. background hypertension is considered as a major public health problem in most countries due to its association with ischemic heart disease which causes cerebrovascular disease and death. objectives the purpose of the present study was to study factors affecti...

In high power high voltage application BLDC motor are widely used because of high efficiency, simple construction, low cost less maintenance and high torque or high output power per unit volume. For driving the BLDC motor we required inverter. PWM inverter which gives good performance. In two level inverter there is a problem of harmonics distortion, lower electromagnetic interference, high DC ...

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...

Both Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) need a traction motor and a power inverter to drive the traction motor. The requirements for the power inverter include high peak power, optimum consumption of energy, low output harmonics and inexpensive circuit. In this paper, a new structure of multilevel inverter with reduced number of switches is proposed for electric vehicle...

A hybrid structured asymmetric switching capacitor multilevel inverter (ASC-MLI) is suggested in this work. The notion behind presenting topology to reduce the device count and DC sources as compared with conventional MLI. step by operating mode of single phase ASC-MLI presented doing slight modifications same configuration used three utility application electric drive. proposed configurations ...
