Title:
THERMAL POWER CONVERTER FOR SUPPLYING ELECTRICITY TO AN AUTONOMOUS APPARATUS WITH LOW CONSUMPTION FROM A VERY SLIGHT DIFFERENCE IN TEMPERATURE
Document Type and Number:
WIPO Patent Application WO1998025333
Kind Code:
A3
Abstract:
An energy converting circuit, boosting the voltage supplied by a low direct voltage source, comprising a self-oscillating circuit, operating at very low voltage, using a voltage boosting transformer generating control signals of two chopper-boosters operating alternately. The circuit including an enhancement-type field effect translator used in synchronous switching with the self-oscillating circuit, which is in serial connection with an inductive resistor to the terminals of the source (1). The transistor being connected to a user circuit via a diode (15, 16). The circuit is used in a device for supplying electricity to appliances and by the production of thermal converters for the utilization of low-voltage thermoelectricity, as well as in a method for the manufacture of thermal converters on an industrial scale.
