In accordance with an embodiment a circuit includes: a plurality of delay elements coupled in series, each delay element including an input node and an output node; a multiplexer having inputs coupled to the output node of each delay element of the plurality of delay elements; and a time measurement circuit including a time amplifier having an input coupled to an output of the multiplexer, and a counter coupled to an output of the time amplifier.

System and method for measuring delays of delay elements

A controller includes a voltage sensing circuit configured to detect a voltage variation across a capacitor of a power converter, and a control circuit configured to calculate a current flowing through an inductor of the power converter based on the voltage variation across the capacitor of the power converter.

Multilevel power converter and control method

A control system, and corresponding method, for a Multi-Level Hybrid Flying Capacitor (MLHFC) converter. The control system includes a controller configured to control an output of the MLHFC converter; a feedback region detector configured to detect a change in a feedback region of the MLHFC converter; and a controller adjuster configured to, in response to the detected change, adjust the control system to counteract instability.

Muti-level hybrid flying capacitor converter control

A circuit having a power converter configured to convert an input voltage to an output voltage; a controller having an inner loop configured to regulate a peak inductor current of an inductor of the power converter to a reference peak inductor current value; and an inductor value measurement circuit configured to determine a value of the inductor based on the output voltage of the power converter and the reference peak inductor current value.
