Abstract

This paper presents a Buck-Boost converter using a MOSFET as a switch fed a dc series motor. The characteristics for step - up and down of the output voltage are studied. It is found that this system posses a good operation performance with a minimum ripple in the output of the motor current and voltage. The mathematical models describing both the open and closed-loop systems are proposed using the differential equations describing the system in different modes of operation for open and closed loop systems. The steady-state, starting- ....etc

This paper proposes a new type of converter called a single-phase Z source matrix buck-boost converter. The converter can invert and amplify with a changed step frequency, and frequency and voltage can be intensified or resigned. In addition, the converter uses a strategy of switching safely, to driving along a current path, which translates into the elimination of spikes on the switches without the need of a circuit of depreciation. The principles of operation of the single-phase Z source matrix proposed buck-boost converter are described, and ....etc

A Multiple-Input Dc-Dc Positive Buck-Boost Converter Topology

Abstract-
A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltage-current characteristics, while achieving low part number and bi-directional operational. Compare to previous multiple-input buck-boost converter, the proposed topology provides positive output voltage; it is capable of bi-directional operation; and it has the capability of operating in buck, boost, and buck ....etc

Abstract.
A novel Zero Voltage Transition (ZVT) technique based closed loop control of Boost Power Factor Correction (PFC) converter with Electro Magnetic Interference (EMI) Filter is presented in this paper. It operates at a xed frequency while achieving zero voltage turn-on of the main switch and zero current turn- off of the boost diode. This is accomplished by employing resonant operation only during switch transitions. During the rest of the cycle, the resonant network is essentially removed from the circuit and converter operation is id ....etc

difference between chopper fed drives and converter fed drives pdf

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed in topic 2, where it was shown that the average output voltage could be varied by periodically switching the battery voltage on and of for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current ....etc

Abstract
This paper presents the performance evaluation of the fuzzy and PI control system applied to Permanent- Magnet Brushless DC Motor (PMBLDCM) with different PWM techniques. At first the comparison analysis is made between SPWM and SVPWM inverter fed PMBLDCM with the implementation of PI controller. From the analysis of Total harmonic distortion (THD) in the inverter current, SVPWM technique was found to be better than SPWM technique. However, the PI controller has some disadvantages such as: high starting ove ....etc
