In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

Traditional DC-DC Boost converters are used in high voltage applications, but they are not economical due to limited output voltage, large voltage ripples, current ripples and power losses. A closed loop control scheme for a simple DC-DC Boost converter in designed and the performance characteristics are studied using MATLAB simulink. The performance of the controller is also studied for variou...

To overcome the conduction and switching losses generated by earlier converter designs, we propose a new genetic algorithm based Cuk converter design which increases the performance of photovoltaic system. The objective is to produce high-efficiency, voltage and current of a PV system with help of GA Controller. The requirement of continuous and controlled flow of voltage has met with the suppo...

This paper proposes a Particle Swarm Optimization method for optimal placement of capacitors in radial distribution system. Because of simple design and low cost radial distribution systems are more popular. But in distribution system, when buses moved away from the substation, the voltage drop increases and losses are also high. Lack of reactive power is the reason for voltage drops and high l...

In this paper, a boost converter with a clamp circuit is proposed for high intensity discharge (HID) lamp application. The clamp circuit provides zero voltage turn on for both main and clamp switches. Compared to conventional boost converters, the proposed converter has the following advantages: (i) high voltage gain without suffering from extreme duty ratio, (ii) low stress on the switches and...

The increasing use and of electricity in Indonesia causes the potential for greater losses transmission distribution system. This many problems that arise, one which is corona Corona mapping can only be detected through several ways, namely sound, light distinctive smell. In this thesis, aim to detect with characteristics a sense smell, then results detection are compared calculated losses. odo...
