摘要： A power converter includes a transformer, a primary switch, an auxiliary switch, first and second resonance capacitors, and a secondary side rectification means. A switch mode power supply is formed to use reflected voltage and parasitic capacitance as an energy source for a transformer resonance. The auxiliary switch effectively exchanges energy between the primary inductance of the transformer and the first and second resonant capacitors. The auxiliary switch effectively switches the transformer resonance between two distinct frequencies. In one embodiment of the invention, the power converter can be, but is not limited to, a flyback converter and further includes a comparator and a driver. The comparator is for detecting the voltage across the second resonance capacitor and the driver is configured to drive the auxiliary switch based on the output state of the comparator. The resonant nature of the converter provides zero voltage (ZVS) for the primary switch as well as for the auxiliary switch.

摘要： An electronic device such as an AC/DC power adapter includes a conductive heat dissipation system. The device contains heat generating components and is powered via power supply leads by an external power supply circuit. The device further contains a thermally conductive mass that is thermally coupled to both the heat generating components and to the power supply leads. When the power supply leads are coupled to receive electricity from the external power supply circuit, heat generated by the device is thermally conducted into the external power supply circuit via the power supply leads.
