Abstract
A system may include an adapter, a charger, and a connector. The adapter is configured to receive an alternating current (AC) signal and generate an adapter signal, the adapter signal being generated based on an up-conversion of the AC signal. The charger is configured to generate a direct current (DC) signal from the adapter signal using one or more energy storage elements and supply the DC signal to a load, in which the adapter signal has a voltage greater than that of the DC signal. The connector is configured to couple the adapter and the charger. In some aspects, the adapter signal is adjusted based on one or more measurements of the DC signal at an output of the charger to maintain a target power for charging the load.
