Theoretical 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 کاملCircuit 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 کاملSingle Phase Converters for Power Factor Correction with Tight Output Voltage Regulation
The flyback converter type single-stage converter and a half wave rectifier with time-multiplexing control (TMC) for power factor correction is proposed. It has the advantage of better magnetic core utilization and better performance for high power applications. The major portion of the input is transferred to the load through ac-dc conversion. And the part of the input power is delivered to th...
متن کاملNonlinear Control of Boost Ac/dc Converters Output Voltage Regulation and Power Factor Correction
We are considering the problem of controlling AC/DC switched power converters of the Boost type. The control objectives are twofold: (i) regulating the output voltage to a desired reference value, (ii) assuring a unitary power factor by enforcing the voltage and the current delivred by the electric network to be in phase. The considered problem is dealt with by designing a nonlinear controller ...
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...
