Universal power adapter and an associated method thereof

A method for providing an output power from a universal power adapter, the method comprising:

• generating the output power, using a power converter, based on a switching frequency of the power converter;
• detecting an output power parameter from the output power, using a sensor;
• computing a control parameter based on a reference parameter and the output power parameter;
• determining if the control parameter is greater than a maximum value of a threshold range or less than a minimum value of the threshold range;
• generating a capacitance switching command if the control parameter is greater than the maximum value of the threshold range or less than the minimum value of the threshold range;
• and
• switching between a plurality of capacitive elements based on the capacitance switching command to maintain the control parameter within the threshold range.

A lighting system comprising:

• a universal power adapter comprising:
• a power converter configured to generate an output power based on a switching frequency of the power converter,
• a frequency controller operatively coupled to the power converter and configured to control the switching frequency of the power converter;
