A new high step-up converter is projected for a photovoltaic system. An asymmetrical interleaved high step-up converter achieves high step up gain through a voltage multiplier module. The voltage multiplier module is organised by a conventional boost converter and coupled inductors. A conventional boost converter is incorporated to achieve a considerably higher voltage conversion ratio. This co...

This paper presents a method for module level State-Of-Charge (SOC) balancing and fault tolerant operation of the Cascaded H-bridge (CHB) converter based battery energy storage system for electric vehicle (EV) application. The proposed methods are based on the multi-dimensional PWM (MDPWM) strategy. It is shown that the proposed methods are conveniently integrated with the PWM generation algori...

This paper presents a boost converter along with a flyback converter. The Zero Voltage Switching (ZVS) technique is used to achieve soft switching. A bidirectional boost converter is connected with an output module as a Parallel Input Serial Output configuration. The flyback converter with Voltage Doubler Rectifier (VDR) acts as an output module. This connection makes a bidirectional boost conv...

A new algorithm is presented to control an MPPT (Maximum Power Point Tracker) through an FPGA (Field Programmable Gate Array). The photovoltaic module was assumed to be connected to a generic load by means of a DC/DC converter controlled through the MPPT. Under these conditions, and for given temperature and solar radiation values, the power supplied by the module was successfully controlled by...

The applied on an axial flux permanent magnet synchronous machine. capable of mechanically mounting converter, sufficiently both machine, combining them into same housing. mechanical thermal design are...

Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–ac inverter. This paper proposes a converter that employs a floating active switch to isolate energy from the PV panel when the ac module is OFF; this particular design protects installers and users fro...

An availability and a reliability prediction has been made for a high-voltage direct-current (HVDC) module of VSC (Voltage Source Converter) containing DC/DC converter, gate driver, capacitor and insulated gate bipolar transistors (IGBT). This prediction was made using published failure rates for the electronic equipment. The purpose of this prediction is to determinate the additional module re...

a. Paul Gray b. Abstract A pipelined, 13-bit, 250-ksample/s (ks/s), 5-V, analog-to-digital (A/D) converter has been designed and fabricated in a 3-μm, CMOS technology. Monotonicity is achieved using a reference-feedforward correction technique instead of (self-) calibration of trimming to minimize the overall cost. The prototype converter requires 3400 mil 2 , and consumes 15 mW c. Design of a ...

A novel integrated buck-flyback non isolated power factor (PF) correction (PFC) converter is proposed in this paper. This new converter is an inherent integration of a buck converter and a flyback converter, which operates in either flyback mode or buck mode according to whether the input voltage is lower or higher than the output voltage. In this way, the dead zones of ac input current in trad...
