For the high-voltage direct-current (HVDC) power transmission system of offshore wind power, DC/DC converters are the potential solution to collect the power generated by offshore wind farms to HVDC terminals. The converters operate with high voltage gain, high efficiency, and fault tolerance over a wide range of operating conditions. In this paper, an isolated ultra-high step-up DC/DC converter with a scalable modular structure is proposed for HVDC offshore wind power collection. A flyback-forward converter is employed as the power cell to form the expandable electrically-isolated modular DC/DC converter. The duty ratio and phase shift angle control are also developed for the proposed converter. Fault tolerance characteristics of the converter are illustrated through the redundancy operation and fault ride-through tests. Redundancy operation is designed to maintain high operation efficiency of the converters and fault ride-through operation improves the converter reliability under harsh operating conditions. Analytical studies are carried out, and a 750 W prototype with three modular cells is built and experimentally tested to verify the performance of the proposed modular DC/DC converter.

Atransformer-less boost converter which provides high voltage gain without utilizing transformer or coupled inductorsandextreme duty cycle is proposed in this paper. Also it is able to cancel the ripples in the input current at a preselected duty cycle, without increasing the number of components.The converter combines the features of boost converter and a three switch high voltage converter. At the input side, two inductors are interleaved for cancelling the input current ripple and at the output side switched capacitor voltage multiplier is used to increase the voltage gain. Feedback control is used to make the output voltage constant in spite of variation in the input or load or both i.e. both line and load regulation is accompanied. This proposed converter configuration helps eliminate the input current ripple and voltage deregulation for low power applications.

Input current ripple from a switching power supply contains considerable low order harmonics, necessitating extra design efforts for reducing the amount of electro magnetic interference.This paper presents a boost converter achieving input current ripple reduction by the proper designing of inductors.This is achieved with minimal number of components.The high voltage gain of this converter eliminates boosting transformers from the circuit.This converter is best suited for renewable energy applications where continous current with minimum ripple is essential.A comparison of switching of the converter with another switching scheme has been obtained for validation. Better line and load regulation is achieved by implementing a closed loop control.Index Terms-Current ripple cancelation, dc/dc converters, pulsewidth modulation.
