Method and apparatus for period detection-based control of regulation control parameter

An apparatus comprising:

• a regulated power converter;
• a control engine configured to generate a control signal to control the regulated power converter based upon a regulation control parameter;
• a period detection system configured to:
• monitor a signal to detect transient events at an output of the regulated power converter, wherein the transient events comprise a first transient event and a second transient event after the first transient event;
• in response to the second transient event, measure a transient event period between the first transient event and the second transient event;
• and
• determine transient event period information based upon the measured transient event period;
• and
• a parameter control system configured to set the regulation control parameter, of the control engine generating the control signal to control the regulated power converter, to a value determined based upon the transient event period information, wherein the setting the regulation control parameter comprises at least one of setting a proportional integral derivative (PID) compensator gain parameter of a PID controller of the control engine, setting an adaptive voltage positioning (AVP) droop level of an AVP controller of the control engine, setting an AVP bandwidth of an AVP filtering module of the control engine or setting an inductor current synthesis parameter of a current monitor of the control engine.
