Abstract
The invention relates to a power supply device comprising: a switch arrangement comprising switches for generating a square wave a switch control arrangement for controlling said switch arrangement, a resonator tank, a rectifier circuitry for rectifying an output from said tank, wherein said switch arrangement is arranged to operate according to an output from said switch control arrangement, wherein said resonator tank is arranged to receive said square wave output, wherein said rectifier circuitry is arranged to provide an output to a potential load, and wherein said power supply device further comprises a burst mode operation arrangement configured to facilitate a standby mode of said power supply, said burst mode operation arrangement comprising a burst mode restriction arrangement configured for receiving and evaluating a first feedback parameter associated with a switch of said switch arrangement and being indicative of the power consumption at said output to said potential load, the burst mode restriction arrangement being configured to disable and enable said burst mode feature based on said evaluation by controlling an output from said burst mode operation arrangement.

50. A method of controlling a standby feature of a power supply device by a burst mode control arrangement, said method comprising:
-
said burst mode operation arrangement receiving a first feedback parameter associated with a switch of said switch arrangement and being indicative of the power consumption at said output to said potential load, continuously averaging said first feedback parameter over a time period to establish a resulting parameter, and continuously comparing said resulting parameter with a first threshold, so as to disable said standby feature if said resulting parameter exceeds said threshold.
