Input current parameters analysis for PFC based on quasi-resonant and conventional boost converters

Application of the Markov Process Equations With Diagnostic of the State of the Mi-8mtv Helicopter Aircraft at Its Operation in Real Operation Modes

“…Для приложений в математической теории надежности [4,5] представляет интерес нахождение аналогичного (32) замкнутого интегрального представления для произво-дящей функции Fi(t; s), как решения уравнений Колмогорова (17) и (18) для процесса отказа одного из двигателей (путем суммирования ряда Фурье (22)), при частных пред-положениях о функции φi = φ(i) [7][8][9][10].…”

A subharmonic stability of power factor correctors with dual-loop control system

“…For the PFC based on a zero-current switching quasiresonant boost converter, discussed in [4], [6], [13], For the PFC based on a conventional boost converter (Fig. 1), e.g.…”

“…Although the most of works are focused on analysis of the input current spectrum [4], [5] and dynamic processes in PFC [6], [7], unfortunately, there is quite limited amount of works devoted to the problems of PFC subharmonic stability [8], [9], [10]. In some articles these issues have not got enough attention [11].…”

“…From the other hand, the PFC system based on zero-current switching quasiresonant boost converter is prospective subject for further research due to its high-frequency operation with high performance [4], [6], [13].…”

“…The input current spectrum analysis for PFC power stages based on conventional and quasi-resonant boost converters was performed in [4] and the regulation accuracy for dual-loop control systems of PFC was estimated in [13], that affects significantly on PFC overall energy efficiency. However, the issue of subharmonic stability of PFC with dual-loop control system remains omitted.…”
