Title:
HIGH-EFFICIENCY SWITCHED-CAPACITOR POWER SUPPLIES AND METHODS
Document Type and Number:
WIPO Patent Application WO/2018/023695
Kind Code:
A1
Abstract:
Switched capacitor (SC) converters with excellent voltage regulation, high conversion efficiency, and good suitability for a wide range of applications are provided. An SC converter can include at least two SC sub-circuits, and at least one of these SC sub-circuits can be of variable gain. One SC sub-circuit can convert the input voltage of the SC converter to an output voltage close to the desired output voltage value for the SC converter, and another SC sub-circuit having variable gain can convert the input voltage to an output voltage with a high resolution of small discrete voltage steps.
