Single-phase half-bridge inverter


Operational Details

Consists of 2 choppers, 3-wire DC source
Transistors switched on and off alternately
Need to isolate the gate signal for Q1 (upper device)
Each provides opposite polarity of Vs/2 across the load

DC Supply Current
If the inverter is lossless, average power absorbed by the load equals the average power supplied by the dc source.
For an inductive load, the current is approximately sinusoidal and the fundamental component of the output ....etc

Current-Fed Resonant Full-Bridge Boost DC/AC/DC Converter
INDIRECT dc/ac/dc converters utilizing an isolation transformer
are widely used in different applications, such as
battery chargers and dischargers, uninterruptible power systems,
alternative energy systems, hybrid electric vehicles, and
medical X-ray imaging.
In the case of the applications where low input voltages have
to be converted to high output voltages, current-fed converters
are used, whereas in the case of higher power applications, fullbridge
boost conve ....etc

THREE PHASE DUAL CONVERTER
Introduction
Thyristor based three-phase controlled rectifiers are widely used in the industry for controlling dc motor drives. Controlled rectifiers offering power conversion from ac to dc are reliable and have higher lifetime compared to other converters. DC motors have higher torque than ac motors and hence are suitable for variable speed and speed reversing applications requiring high torques. Although the operation of controlled rectifiers is simple, the realization of the converter control circuit is complex i ....etc

Abstract
A new isolated current-fed pulse width modulation dc-dc converter-current-fed dual-bridge dc-dc converter-with small inductance and no dead time operation is presented and analyzed. The new topology has more than 3times smaller inductance than that of current-fed full-bridge converter, thus having faster transient response speed. Other characteristics include simple self-driven synchronous rectification, simple housekeeping power supply, and smaller output filter capacitance. Detailed analysis shows the proposed converter can have eit ....etc

Since the fuel cell system has slow dynamics of nature, it is recommended that you have an additional auxiliary power, for example, ultra-capacitors or batteries during the transition to improved performance in energy and transport applications. The use of ultracapacitors and bi-directional converter with a fuel cell system may be one of the possible solutions to the problem of slow dynamics of fuel cell systems. In this article we present a combined small AC signal equivalent circuit model of bidirectional converter in PEM fuel cell, and the c ....etc

single phase dual converter application

The high-level schematic shown below is built from six main blocks. The DC motor, the two single-phase full converters, and the bridge firing unit are provided with the Simscape Power Systems library. More details on these blocks are available in the reference sections of these blocks. The two other blocks are specific to the Electric Drives library. These blocks are the speed controller and the current controller. They allow speed or torque regulation. A regulation switch block allows you to toggle ....etc
