Modular Design of APFC: A Feasibility Study

نویسندگان

چکیده

The feasibility of producing a modular Active Power Factor Correction (APFC) system was studied analytically and experimentally. It is shown that the novel control scheme that does not need the sensing of the input voltage is highly compatible with the modular concept. Modularity is achieved by aggregating practically all the electronic in an IC or hybrid unit that may also include the power switch. This unit plus a line rectifier, inductor and bus capacitor are all that it takes to form an APFC system. This plug and play solution will greatly simplify and reduce the cost of the design and manufacturing of APFC front ends.

Toward A Plug-And-Play Approach For Active Power Factor Correction

The feasibility of producing a modular Active Power Factor Correction (APFC) system was studied analytically and experimentally. It is shown that the novel control scheme that does not need the sensing of the input voltage is highly compatible with the modular, plug-and-play concept. Modularity is achieved by aggregating practically all the electronics in an IC or hybrid unit that may also incl...

Investigation the status of instructional design with modular method in medical education

Background and Goal: Modular method is a form of in-service training which provides job skills into a form of independent training of audiences. Each of modular provides specific skill and at the same time besides the other modular led to a new and comprehensive skill. In fact, any educational modular is a set of knowledge, attitudes and skills which by using them it can be possible to do ...

A direct comparison of anterior prefrontal cortex involvement in episodic retrieval and integration.

Retrieval of information from episodic memory reliably engages regions within the anterior prefrontal cortex (aPFC). This observation has led researchers to suggest that these regions may subserve processes intimately tied to episodic retrieval. However, the aPFC is also recruited by other complex tasks not requiring episodic retrieval. One hypothesis concerning these results is that episodic r...

Benefits of Silicon Carbide Schottky Diodes in Boost APFC Operating in CCM

Boost derived Active Power Factor Correction (APFC) imposes high stress on the main diode and main switch due to the high reverse voltage which may result in a very high reverse current. This study analyses the engineering requirements of the diode and transistor in APFC applications and compares a design that uses a fast silicon diode plus lossless snubber to a design with a Silicon Carbide (S...

Modular approach for an ASIC integration of electrical drive controls

VLSI circuits design allows today to consider new modes of implementation for electrical controls. However, design techniques require an adaptation effort that few designers, too accustomed to the software approach, provide. The authors of this article propose to develop a methodology to guide the electrical designers towards optimal performances of control algorithms implementation. Thus, they...
