Power supply system based on heat-electric cell

Abstract

The invention provides a power supply system based on a heat-electricity tank, and the system comprises the heat-electricity tank, a first control circuit, an energy storage module, a second control circuit, and a load. The heat-electricity tank comprises a hot end, a cold end, and a heat-electricity piece disposed between the hot end and the cold end. The hot end comprises a water inlet and a water outlet, and the water inlet is communicated with a primary heat source, and the water outlet is communicated with a secondary heat source. The first control circuit comprises a Boost conversion module, a current detection module, a PWM control module, and a voltage sampling module. The Boost conversion module is electrically connected with the heat-electricity piece, and the current detection module is used for obtaining the current information of the Boost conversion module. The voltage sampling module is used for obtaining the voltage information of the heat-electricity tank, the energy storage module and the current detection module, and transmits the voltage information to the PWM control module. The PWM control module controls the Boost conversion module to charge the energy storage module according to the voltage information, and the load is electrically connected with the energy storage module. The second control circuit is used for controlling the water inlet according to an output voltage of the energy storage module.

Description

technical field [0001] The invention relates to a power supply system based on a thermal-electric cell. Background technique [0002] Thermoelectric materials are functional materials that can convert thermal energy and electrical energy. The Seebeck effect discovered in 1823 and the Peltier effect discovered in 1834 provide a theoretical basis for the application of thermoelectric energy converters and thermoelectric refrigeration. With increasing interest in space exploration, advances in medical physics, and increasingly difficult resource exploration and exploration activities on Earth, there is a need to develop a class of power systems that can self-supply and leave unattended, and thermoelectric power generation is particularly suitable for these applications. [0003] The use of natural temperature difference and industrial waste heat can be used for thermoelectric power generation. It can use the non-polluting energy existing in nature and has good comprehensive soc...
