A novel diode-capacitor voltage multiplier for increasing the voltage of photovoltaic cells
2008 11th Workshop on Control and Modeling for Power Electronics, 2008A new scheme of a diode-capacitor network, used as a DC voltage multiplier is proposed. The circuit operates in combination with a high-frequency switch. In contrast to the present similar circuits, during the operational process the capacitors are not shortened by the switch and therefore the large discharge current stresses donpsilat influence the ...

High Step-Up Soft-Switched Converters Using Voltage Multiplier Cells
IEEE Transactions on Power Electronics, 2013In this paper, a soft-switched dc-dc converter using voltage multiplier cells is proposed for high-step up application. The proposed converter has the following advantages: 1) doubled voltage conversion ratio of the basic configuration (N = 1) compared to the conventional boost converter; 2) zero voltage switching turn ON of switches and zero current ...

Steady state analysis of voltage multiplier ladder switched-capacitor cell
2016 12th IEEE International Conference on Industry Applications (INDUSCON), 2016Switched capacitor converters have become an alternative for high gain power conversion. The ladder switched capacitor cell is used for voltage multiplying and, when associated with other conventional converters in hybrid topologies, it does not need any additional controlled switches for the cell. There are solutions in literature for the steady state

Switched-Capacitor-Cell-Based Voltage Multipliers and DC–AC Inverters
IEEE Transactions on Industry Applications, 2012In this paper, several modular converter topologies based on a switched-capacitor-cell concept are introduced for high-power applications. Two types of switched-capacitor cells, including the full cell and the half-cell, are discussed. The full cell can be used for dc-ac inversion, and the half-cell is utilized in both dc-dc and dc-ac applications.
