The Cost

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 include the power switch. This unit plus a line rectifier, inductor and bus capacitor are all that it takes to form an APFC system. It is demonstrated that dynamic stability is assured by the proposed inherent robust control method. This plug-and-play solution will greatly simplify and reduce the cost of the design and manufacturing of APFC front ends.

Line Current

Nowadays the use of electronic equipment finds a progressive development in the modern world. Hence it becomes a mandate to check whether the harmonic content of line current of any electronic device which is connected to the ac supply meets the appropriate standards. This demand is satisfied by implementing the Power Factor Correction (PFC) circuit in order to make the input current to be in sinusoidal in nature and in-phase with the input voltage. Numerous solutions are available to make the line current almost sinusoidal. This paper describes an isolated power factor corrected power supply that utilizes the leakage inductance of the isolation transformer to provide boost inductor functionality. The bulk capacitor is in the isolated part of the power supply allowing for controlled startup without dedicated surge limiting components. A control method based on switch timing and input/output voltage measurements is developed to jointly achieve voltage regulation and input power factor control.
