“…Many reports have discussed the control of PFC AC/DC boost converters. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) A conventional control method uses voltage outer and current inner loops to trace the input voltage, input current, and output DC voltage with the average current control method. (1) However, the control by this method is complex and requires many detection components, which increases the circuit volume, cost, and complexity, and UC3854 is typically used as the control chip.…”

“…(1) However, the control by this method is complex and requires many detection components, which increases the circuit volume, cost, and complexity, and UC3854 is typically used as the control chip. Another control method is one-cycle control, (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) which does not need to detect the input voltage and does not use a multiplier, but it only uses a trigger signal control of an integrator and compares a sawtooth wave with the current detesting value. Finally, the control is relatively simple through the set-reset (SR) flip-flop control converter duty cycle and can significantly reduce the circuit size and cost.…”

In this paper, an improved one-cycle control is proposed for an AC/DC boost converter with power factor correction (PFC) using logic and analogy circuits. The proposed improved onecycle control method realizes features that are similar to those of the conventional one-cycle method without using a sense input voltage and a multiplier. It can also promote the stability of the converter. The adjustable maximum duty cycle limit of the converter is designed to limit the maximum duty cycle by adopting the logic and analogy circuits. According to the analysis of the modified one-cycle control method, the suitable circuit component parameters of the converter can be designed for the one-cycle control AC/DC PFC boost converter. Finally, a modified one-cycle control AC/DC PFC boost converter with input ACs of 90, 110, 220, and 260 V, an output DC of 400 V, and an output power of 500 W was built to verify the accuracy and feasibility of its performance.

A new on-line parameter tuning method for digitalcontrolled PFC with transition current mode control is proposed in this paper. The proposed method copes with the parameter variation issue which results in discontinuous current mode operation and larger current ripple. The proposed method is to give one more current sample in one sampling period in order to estimate the inductance of boost inductor on line and thereby tuning the parameter of controller. It will be shown by experimental results that the proposed on-line parameter tuning method can retain transition current mode operation even under full load condition and slightly increase the converter efficiency.I.

“…To achieve good input current shaping over the complete load range, a linear CCM controller, a non-linear DCM controller and an operation mode selection circuit are employed in [9]. This analog control scheme is based on one-cycle control where the average inductor current is controlled to be proportional to a carrier signal that is selected by the operating mode selection circuit.…”

Boost power factor correctors (PFCs) and digital average current controllers are usually designed for continuous conduction mode (CCM). However, discontinuous conduction mode (DCM) appears at light loads in the inductor current near zero crossings of the input current, resulting in input current distortion. It is caused by inaccurate average current values obtained in DCM. The inductor current goes to zero before the end of the switching period. Thus, the average is not given by sampling in the middle of the rising edge of the inductor current. In addition, the linear CCM PFC controller is unable to ensure input current shaping in DCM whereby the converter exhibits non-linear characteristic. This paper proposes a simple digital DCM control scheme for boost PFC. DCM current control is achieved with minimal changes to the CCM control structure, and is easy to implement digitally. Good input current shaping is achieved in both CCM and DCM.Index Terms-power factor correctors (PFCs), discontinuous conduction mode, input current distortion, digital DCM current control, boost PFC 978-1-4244-5287-3/10/$26.00 ©2010 IEEE
