Classification: CPC H  Y | IPC H

Claim 14:
15. A method for generating a bus voltage for powering an electrical load, the method comprising:
determining an output power of a power converter circuit, the power converter circuit comprising a semiconductor switch, a control circuit, and a bus capacitor;
generating a drive signal for rendering the semiconductor switch conductive and non-conductive to charge the bus capacitor, wherein the drive signal is characterized by an operating period that is limited to a minimum operating period;
wherein, when the output power is greater than a first threshold, the method further comprises adjusting the minimal operating period with respect to time in a range between a first upper value that is greater than a first operating period value and a first lower value that is less than the first operating period value; and
wherein, when the output power is less than a second threshold, the method further comprises adjusting the minimal operating period with respect to time in range between a second upper value that is greater than a second operating period value and a second lower value that is less than the second operating period value.
