Single-switch cell voltage equalizer using voltage multipliers for series-connected supercapacitors
2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012A novel single-switch cell voltage equalizer using voltage multipliers for series-connected supercapacitors (SCs) is proposed. Since the proposed equalizer can operate with a single switch at a fixed duty cycle when operated in discontinuous conduction mode (DCM), the circuit complexity can be reduced significantly when compared with conventional ...

A novel interleaved boost converter with voltage multiplier cell
2014 IEEE 2nd International Conference on Electrical Energy Systems (ICEES), 2014The input supply available from renewable sources like solar and fuel cells will be at low level. This must be stepped up considerably for practical utilization. In this paper, a boost converter derived topology consisting of two interleaved stages and five voltage multiplier cells (VMC) is presented.

A Novel Z-source Inverter with Voltage Multiplier Cells
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019The traditional single-stage boost inverter can overcome the disadvantages of incompatibility between boost and inverter, owing to the structure of the topology, the boosting capability of this type of circuit is limited by the modulation factor M, and cannot fully exploit its advantages.

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 ...

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.
