Abstract: An electrical adapter can include a rectifying circuit configured to receive an AC power input, a power factor corrector (PFC) circuit coupled with an output of the rectifying circuit, and a capacitive component coupled with an output of the PFC circuit. The electrical adapter can further include a DC-DC converter circuit coupled with an output of the capacitive component and configured to provide a power output of the electrical adapter, and an impedance-measuring circuit coupled with the power output and configured to measure impedance of a cable connected to the power output. The DC-DC converter circuit can be configured to adjust power of the power output based on the measured impedance.
