“…The third-harmonic current kR s i 3 can be extracted by sampled three-phases input inductor currents Based on (2), the modified control key (5) for the rectifier can be obtained. From (13), it is clear that the signals which are obtained by injecting the third-harmonic signal kR s i 3 into the three-phases sampling currents are as modulation signals and the SAPWM is proposed to introduce in the conventional OCC strategy. Blasko [24] has shown the modulation waveform of SAPWM is equivalent with the space vector PWM (SVPWM), but the algorithm and realisation of SAPWM is more easy and convenient than the SVPWM, whether in the analogy circuit or digital circuit.…”

The saddle pulse-width modulation (PWM) that can be obtained by injecting third harmonic current into sampled three-phase input currents is proposed to introduce in the conventional one-cycle control (OCC) strategy-based three-phase PWMrectifier on this study. In addition, for the three-level boost-type neutral-point-clamped structure rectifiers such as threephase Vienna rectifier, the fluctuation in the neutral-point-potential (NPP) is analysed under modified OCC strategy. The proposed control scheme can not only improve the utilisation of DC bus voltage and the efficiency of converter without sacrificing the advantages of the conventional OCC scheme, such as no phase-locked loop and constant switching frequency, but also is beneficial to suppress the ripple in the DC-link voltage. Moreover, the neutral-point voltage loop is added in the proposed OCC scheme, and the neutral-point voltage controller is employed for controlling the unbalance DC voltage in the NPP which caused by the non-uniformity of parameters of components. The validity of the theoretical analysis and feasibility of the modified OCC strategy are verified by system simulation and experimental results based on a 5-kW prototype.

“…To simplify the control structure of the grid-connected systems, one-cycle control (OCC)-based three-phase PWM boost-type rectifiers have been proposed [10][11][12][13][14][15][16][17]. This control technique does not require the service of the PLL for current reference generation, which is useful to improve the robustness of controller.…”

Bu çalışmada, Azaltan ve Yükselten da-da dönüştürücüleri için sabit bir anahtarlama frekansında çalışan Tek Çevrim denetim yöntemi sunulmaktadır. Önerilen denetleyici, doğrusal olmayan denetim türündedir ve her anahtarlama periyodunda anahtarlanan değişkenin ortalama değerini, referans işaretine eşit veya referans işaretiyle orantılı olmasını sağlamak için anahtarın doluluk oranını ayarlamaktadır. Bu denetim yönteminde, denetim referansı ile anahtarlanan değişkenin ortalama değeri arasında sabit bir hata veya dinamik hata olmadığı için sürekli durum hatası sıfırdır, aşma yoktur ve geçici cevap hızlıdır. Yük ve kaynak geriliminde görülen ani değişikler altında, önerilen denetleyicinin geçerliği PSIM benzetim programı ile doğrulanmıştır.

The single-stage flyback power factor correction (PFC) converter is well applied in medium and low power occasion such as adapters or LED drivers. Usually, the flyback PFC converter is preferred to operating in boundary conduction mode (BCM) for achieving high power factor (PF) and high efficiency at the same time. However, the conventional BCM control scheme such as input voltage tracking control or constant on-time control (COT) could not achieve unit PF for the flyback PFC converter. As input voltage increases, the PF and the total harmonic distortion (THD) of flyback converter deteriorate seriously. In this paper, a variable-frequency one-cycle control (VF-OCC) for BCM flyback single-stage PFC converter is presented to achieve unit power factor. Detailed theoretical analysis and design consideration for the VF-OCC are described. At last, two 54W/1.5A laboratory prototypes with two operation strategies have been built up. Experiment results show that the BCM flyback converter with VF-OCC can achieve high PF and low THD over universal input voltage range.
