Control Strategy for the Discharge Phase of an Ultra-High Voltage (>7kV) Bi-Directional Flyback Converter Driving Capacitive Actuators

Yves Perriard, Alexis Boegli, Raphaël Johannes Charles Mottet

Dielectric Elastomer Actuators (DEAs) require ultra high voltages in the order of several kilo volts to operate. To supply such voltages, a DC-DC flyback converter topology was selected. One of the main advantage of using such a structure is the possibilit ...

Two-Port Low-Power Gain-Cell Storage Array: Voltage Scaling and Retention Time

Andreas Peter Burg, Pascal Andreas Meinerzhagen, Rashid Iqbal

The impact of supply voltage scaling on the retention time of a 2-transistor (2T) gain-cell (GC) storage array is investigated, in order to enable low-power/low-voltage data storage. The retention time can be increased when scaling down the supply voltage ...
