Circuit theory of power factor correction in switching converters
This paper discusses the circuit theory aspects of power factor correction in switching converter circuits. The discussion begins with an examination of the requirement of power factor correction in dc=dc converters. Using the concept of zero-order converter circuits, su cient conditions for a dc=dc converter circuit to provide power factor correction are derived. The duality principle is appli...
متن کاملZero-Order Switching Networks and Their Applications to Power Factor Correction in Switching Converters
This paper addresses the requirements of networks containing linear inductors, capacitors and ideal switches for synthesis of zero-order input impedance. Sufficient conditions for achieving zero-order input impedance are stated in terms of the network topology and the switching sequence. Such networks have direct practical relevance to power factor correction (PFC). Based on zero-order switchin...
متن کاملTheoretical Study of Switching Power Converters with Power Factor Correction and Output Regulation
This paper discusses a systematic method for deriving basic converter configurations that achieve power factor correction (PFC) and voltage regulation. The discussion begins with a general three-port representation of power supplies that provide PFC and voltage regulation. Based on this representation and a power flow consideration, a systematic procedure is derived to generate all possible min...
متن کاملIntermittent Chaotic Operation in Switching Power converters
In the process of designing and constructing switching power converters, chaotic operations are often observed intermittently between long periods of regular operations. In practice, such intermittent chaotic operations can be eliminated by incorporating appropriate design measures to combat interference of spurious signals. In this paper, we explain the mechanism that causes “intermittent” cha...
متن کاملComplex Behavior in Switching Power Converters
Power electronics circuits are rich in nonlinear dynamics. Their operation is characterized by cyclic switching of circuit topologies, which gives rise to a variety of nonlinear behavior. This paper provides an overview of the chaotic dynamics and bifurcation scenarios observed in power converter circuits, emphasizing the salient features of the circuit operation and the modeling strategies. In...
