“…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.…”

“…Conventional one-cycle control methods can be broadly divided into the following two categories: the first category uses the output DC voltage error to obtain a continuous count-down sawtooth wave to be compared with the measured inductance current and to determine the duty cycle of the converter switch (2)(3)(4)(5) with IR1155S typically used as the control chip. The second category uses the output DC voltage error to obtain a continuous count-up sawtooth wave to be compared with the measured inductance current and to determine the duty cycle of the converter switch.…”

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.

Power Factor Correction (PFC) is an essential feature of many AC/DC Power Electronics products. The issue of increasing the value of the Power Factor (PF) and increasing efficiency of transferring the power in such applications motivated this work. The integrated circuit NCP1014 was used to implement hardware of 20 W Discontinuous Conduction Modes Power Factor Correction (DCMPFC) prototype to be suitable to applications that require good performance, small size, low cost and high efficiency.In this work, a known inductive load is used, and measured the power factor with and without the proposed correction circuit, the results showed an improvement of the power factor up to 40%.The presented results that have been tested in this paper were implemented in a laboratory to show the effectiveness of the proposed system.
