| Abstract: | New high voltage watt-hour meters have the advantages of high precision measurement, low power consumption, informationization, intelligence, etc. which are selected in more and more applications. This paper researched on the power supply of the new metering devices, designed a new power management unit based on induction current energy harvesting. The unit introduced a smart electrical energy storage function between the voltage regulator and the energy harvesting coil, made sure the metering devices can operate stably, avoided the metering losses due to the power off of the metering devices. The experimental results showed that the storage electrical energy could supply for 4.5 hours without the energy harvesting. |
