Abstract
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.

A control system for a Multi-Level Hybrid Flying Capacitor (MLHFC) converter, the control system comprising:
- 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 by monitoring a property of a flying capacitor voltage of the MLHFC converter and a property of a control signal of the controller;
- and
- a controller adjuster configured to, in response to the detected change, adjust the control system to counteract instability.
A control system for a Multi-Level Hybrid Flying Capacitor (MLHFC) converter, the control system comprising:
- 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 to operate independent of parameters of the MLHFC converter, wherein the parameters comprise a load current, an input voltage, a switching frequency, and an inductance;
- and a controller adjuster configured to, in response to the detected change, adjust the control system to counteract instability.
A method of a control system controlling a Multi-Level Hybrid Flying Capacitor (MLHFC) converter, the method comprising:
- controlling, by a controller, an output of the MLHFC converter,
- detecting, by a feedback region detector, a change in a feedback region of the MLHFC converter by monitoring a property of a flying capacitor voltage of the MLHFC converter and a property of a control signal of the controller;
- and
- adjusting, by a controller adjuster, in response to the detected change, the control system to counteract instability.
