Abstract
(A1) Schaltanordnung zum Betrieb eines Hochspannungsaktuators (3), welche eine Hochspannungsbatterie (4) umfasst. Die Hochspannungsbatterie (4) ist dabei vorteilhafterweise klein dimensioniert. Die Hochspannungsbatterie (4) kann aufladbar sein und ueber ein externes Ladegeraet geladen werden. Durch zusaetzliche Elemente wie eine Niederspannungsquelle (1) und einen Spannungswandler (2) ergibt sich eine alternative Lademoeglichkeit. Die beanspruchten Ausfuehrungsformen der Hochspannungsbatterie (4) koennen auch in anderen Schaltanordnungen eingesetzt werden.

 

DE 102007004914 A1 UPAB: 20081002 NOVELTY - The circuit arrangement has a high voltage actuator (3), where a high-voltage battery (4) e.g. electrochemical cell, is connected with the high voltage actuator by a switching unit i.e. microelectronic mechanical system relay (5), where the high-voltage battery is chargeable. A voltage transformer (2) converts a voltage of a low-voltage source (1) into a high-voltage. The low-voltage source and the voltage transformer are connected with the high-voltage battery and/or the high-voltage actuator by the switching unit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating and charging a chargeable high-voltage battery. USE - Switching arrangement for use in a micro fuel cell system, a drug dosing system and a hand pipette system (all claimed) for controlling and operating a high-voltage actuator e.g. micromechanical actuator such as micro pump, micro valve, and piezo pump. ADVANTAGE - The high-voltage battery is connected with the high-voltage actuator, thus facilitating the supply of the required high-voltage to the high-voltage actuator in real-time without delay in a reliable manner and at the same time providing a high efficiency for the high-voltage actuator.
