Implementation of Full-Bridge Current-Fed Resonant Boost Converter using PIC microcontroller
ABSTRACT
This paper presents a current-fed full-bridge boost DC-ACDCconverter with transformer isolation operating withoutswitching power dissipation. The output voltage is regulatedby dc-ac converter whose frequency changes with a constantturn-off time of transistors. The proposed converter is devoidof parasitic oscillations, as all of the parasitic capacitancesand inductances are included in a resonant tank circuit. Themain advantage of such ....etc

ABSTRACT
Due to efficient control methods, DC motors are widely used motors to drive the loads in industry. Among the different control techniques for the DC motor speed control, armature voltage control method using Pulse Width Modulation (PWM) technique is the best one. We can realize the PWM control method u ....etc

ECE 8830 - Electric Drives
Introduction
Current-fed inverters requires a “stiff” constant current source input - thus are sometimes referred to as CSI (current source inverters or current stiff inverters).

A large inductance can be used to change a variable voltage input to a variable current input.

VSI-inverters and CSI-inverters are dual to each other.
Introduction (cont’d)
Power semiconductor devices used in CSI inverters must be able to withstand large reverse voltag ....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 conv ....etc

Abstract
This paper deals with a reduced rating delta-polygon
autotransformer based twenty-four-pulse ac-dc converter feeding
variable frequency induction motor drives (VFIMD's) for
improving power quality at the point of common coupling (PCC).
The proposed twenty four-pulse ac-dc converter is realized on the
principle of dc ripple re-injection technique for harmonic
mitigation. The design of the proposed autotransformer is
developed alongwith the necessary modifications required for
making it suitable for retrofit applications ....etc
