Schaltanordnung

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
