Report on Dynamic modeling and operation of Microgrid with MI CUK Converter.

Recommandé

This paper presents a transformer less single-stage single-switch ac/dc converter suitable for universal line applications (90–270 Vrms). The topology consists of a buck-type power-factor correction (PFC) cell with a buck–boost dc/dc cell and part of the input power is directly coupled to the output after the first power processing. With this direct power transfer and sharing capacitor voltages, the converter is able to achieve efficient power conversion, high power factor, low voltage stress on intermediate bus (less than 120 V) and low output voltage without a high step-down transformer. The absence of transformer reduces the size of the circuit , component counts and cost of the converter. Unlike most of the boost-type PFC cell, the main switch of the proposed converter only handles the peak inductor current of dc/dc cell rather than the superposition of both inductor currents. Tight voltage regulation is provided by using PID controller. Detailed analysis and design procedures and simulation of the proposed circuit are given .

The electric power supplied by a photovoltaic power generation system depends on the solar radiation and temperature. Designing efficient PV systems heavily emphasizes to track the maximum power operating point. This work develops a three-point weight comparison method that avoids the oscillation problem of the perturbation and observation algorithm which is often employed to track the maximum power point. Furthermore, a low cost control unit is developed, based on a single chip to adjust the output voltage of the solar cell array.
