温差发电供电装置
摘要：
一种温差发电供电装置有温差发电片，低温侧连有散热片，温差温差发电片的电源输出端连有TPS61201同步升压转换器，同步升压转换器的EN端、PS端和UVLO端接在其输入端VIN端上，FB端接在其输出端VOUT端上，GND端和PGND端接地，VIN端的VOUT与地之间分别连有10μF的电容器，VAUX端与地之间连有0.1μF的电容器，VIN端与L端之间连有1.5～4.7μH的线圈，温差发电片的电源输出端连在同步升压转换器的VIN端和地线上。本发明温差发电片的低温侧连有散热片，有利于温差发电片发出较高的电压；温差发电片的输出端连有TPS61201低输入电压同步升压转换器，当温差发电片的温差变化时，仍能在其输出端产生电压值稳定的输出电压。
摘要（英）：

The invention relates to a temperature difference power generation type power supply device which comprises a temperature difference power generating sheet. A cooling sheet is connected at the lower temperature side, the power source output end of the temperature difference power generating sheet is connected with a TPS61201 synchronous boost converter, the EN end, the PS end and the UVLO end of the synchronous boost converter are connected with the input VIN end, the FB end is connected with the output VOUT end, the GND end and the PGND end are grounded, a 10 muF capacitor is connected between the VIN end and the ground and another 10 muF capacitor is connected between the VOUT end and the ground, a 0.1 muF capacitor is connected between the VAUX end and the ground, a 1.5-4.7 muH coil is connected between the VIN end and the L end, and the power source output end of the temperature difference power generating sheet is connected to the VIN end of the synchronous boost converter and the ground wire. The cooling sheet is connected to the lower temperature side of the temperature difference power generation sheet and facilitates the temperature difference power generation sheet to emit higher voltage. The output end of the temperature difference power generating sheet is connected with the TPS61201 low-input-voltage synchronous boost converter. When the temperature difference of the temperature difference power generating sheet changes, an output voltage with stable voltage value can still be generated at the output end.
