An online capacitance estimation method based on DC component applied in PFC converter with split-capacitor
نویسندگان
چکیده
Inaccurate capacitance significantly increases the DC-Link ripple voltage of active power decoupling circuit (APDC). To solve this problem, a high-precision online estimation method is proposed. This converts AC components capacitor into sum DC component and with 8 times grid frequency, which beneficial to extraction component. replaces effectively eliminate periodic mutation, accurately estimate capacitance. Based on capacitance, controlled set scope. Experimental results verify effectiveness proposed method.

Recent advances in low-power circuits have enabled mm-scale wireless systems [1] for wireless sensor networks and implantable devices, among other applications. Energy harvesting is an attractive way to power such systems due to limited energy capacity of batteries at these form factors. However, the same size limitation restricts the amount of harvested power, which can be as low as 10s of nW ...
