Title:
THERMALLY DRIVEN POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO2003015186
Kind Code:
A3
Abstract:
The invention relates to a power supply (SV) that comprises at least one thermoelectric converter (1) with an energy accumulator (2) mounted downstream thereof, and a low-power activation unit (3) for monitoring the charge condition of the energy accumulator (2) and for the charge-dependent switching of an output signal of the energy accumulator (2). The inventive power supply is especially suitable for click sensors, and the activation unit is designed as an extremely power-saving element, for example by means of normally off FETs.
