Claim:
1. A controller for a power converter having a plurality of switches couplable to respective electrical devices, the controller comprising: a switch activating unit for activating the switches; a frequency varying unit; a comparator configured to compare respective electrical parameters of the electrical devices with respective reference electrical parameters to obtain associated results; and a selector configured to select based on the results, either no switches or at least one switch to be activated to enable at least two electrical devices to be electrically connected, wherein the activation is performed on receipt of a signal pulse, and if no switches are selected, the signal pulse is skipped by the switch activating unit to reduce power consumption of the controller, wherein based on the results, a frequency of the signal pulse is varied by the frequency varying unit to further reduce power consumption of the controller, and wherein the comparator and selector are configured to be switched off prior to receipt of the signal pulse.
