A Novel Parallel Current-sharing Control Method of Switch Power Supply
A novel parallel current-sharing control method of switch power supply is proposed, on the basis of a detailed analysis of several common parallel current-sharing control methods and recent related patents. Only the current of switch power modules with maximum and minimum output current will be regulated, which is selected by the extreme current selection circuit in this method. Four cases with...
متن کاملA parallel resonant constant current power supply
In the past, resonant converters have generally been analyzed and characterized for constant output voltage power supplies. When applied to power supplies, in which output current is regulated, the topological requirements of a resonant converter differ. This means, a resonant converter topology not suitable for constant voltage power supplies may become attractive for constant current power su...
متن کاملA Novel Reference Current Calculation Method for Shunt Active Power Filters using a Recursive Algebraic Approach
This paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (SAPFs). This method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. Next, the amplitude of the reference mains currentis computed with ...
متن کاملOptimal Sensorless Four Switch Direct Power Control of BLDC Motor
Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...
متن کاملCurrent Sharing and Phase Alignment for Independent Parallel Power Supplies
The trend in next-generation switched-mode power supplies will lead to modular, scalable solutions which can deliver power efficiently over a wide range of operation. Multiple parallel power stages, often called “phases”, are necessary to meet these requirements. This paper details a new approach to introduce more control features like phase-alignment, current sharing and phase shedding, which ...
