Power supply configurations and non-linear control, switching period adjustment and current control based on error signal

A method comprising:

• producing an output voltage via supply of output current from at least one power supply phase of a power supply to power a load;
• generating a switching period adjustment signal based on an error voltage indicating a difference between the output voltage and a setpoint voltage;
• deriving a current control signal from the error voltage;
• and
• generating a pulse width modulation signal of a first power supply phase based on the switching period adjustment signal and the current control signal.

Computer-readable storage hardware having instructions stored thereon, the instructions, when executed by computer processor hardware, cause the computer processor hardware to:

• produce an output voltage via supply of output current from at least one power supply phase of a power supply to power a load;
• generate a switching period adjustment signal based on an error voltage indicating a difference between the output voltage and a setpoint voltage;
• derive a current control signal from the error voltage;
• and
• generate a pulse width modulation signal of a first power supply phase based on the switching period adjustment signal and the current control signal.
