This paper presents a high-efficiency management circuit using multi-winding up-conversion current transformer (CT) for power line energy harvesting. Due to sharing same loop for matching and charging in low working frequency (50Hz), the traditional matching circuit of the CT has a low Q value and low magnetoelectric(ME) efficiency, and cannot be used in both weak power-line current and heavy load. A multi-winding CT up-conversion matching circuit with a higher Q value is developed. Higher charging power (>175%), and larger ultimate charging voltage (>150%) in the weak power-line current (1A-100A) can be obtained by using the independent up-conversion resonant matching loop. The matching circuit can efficiently work at a wider load capacitance. In order to drive the wireless sensor with a higher consumption power, an instantaneous discharging circuit is developed suitable for weak energy harvesting (<700 μW). The instantaneous discharging circuit can accumulate weak energy from the CT transducer during a long period, and provide a higher power output in a very short time. The management circuit can drive wireless sensor with an output power of 60 mW at a distance of over 40 m. The multi-winding high-efficiency up-conversion management circuit can be used in many other low-frequency energy harvesters. |
