High boost converter using voltage multiplier
TL;DR: In this paper, a high boost converter with a voltage multiplier and a coupled inductor was proposed to boost low input voltage to high voltage output with low duty cycle, and the secondary voltage was rectified using voltage multiplier.
Journal ArticleDOI
A Novel Grid Synchronization PLL Method Based on Adaptive Low-Pass Notch Filter for Grid-Connected PCS
TL;DR: This paper proposes a novel low-pass notch filter PLL (LPN-PLL) control strategy to synchronize with the true phase angle of the grid instead of using a conventional synchronous reference frame PLL, which requires a d-q-axis transformation of three-phase voltage and a proportional-integral controller.
Proceedings ArticleDOI
High voltage switch using series-connected IGBTs with simple auxiliary circuit
TL;DR: In this paper, a simple and reliable voltage-balancing circuit for the series operation of devices to overcome the disadvantages of solutions presented so far, such as complex control or circuit, low reliability, and limited number of connected devices to be connected.
Journal ArticleDOI
A New Topology With High Efficiency Throughout All Load Range for Photovoltaic PCS
TL;DR: The proposed topology can significantly reduce the converter rated power and increase the efficiency of total photovoltaic (PV) system and the total system efficiency at light load is dramatically improved.
Journal ArticleDOI
Novel zero-voltage and zero-current-switching full bridge PWM converter using transformer auxiliary winding
TL;DR: In this paper, a zero voltage and zero current switching (ZVZCS) full bridge (FB) PWM converter is proposed to improve the demerits of the previously presented ZZCS-FB-PWM converters, such as use of lossy components or additional active switches.
