摘要： An electric vehicle solar charging system is disclosed, comprising a photovoltaic system or a DC source to transmit DC electricity to an electric vehicle via DC/DC conversion system. The DC/DC conversion is configured to directly transmit power to a battery pack configured to power the electric vehicle through the electric vehicle's DC charging inputs. This electricity can be supplemented by building battery or energy storage systems with DC output, or by DC electricity converted from AC which was supplied by AC sources. The combined circuit can be further modified by an in-line DC/DC converter at output if necessary, which also may be a bidirectional converter to supply energy from the EV back to the house load through a connected AC/DC inverter. When no DC is available, an AC power source can optionally provide supplemental power to the electric vehicle directly through the AC charging inputs.

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.

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： A wireless light switch harvests energy for ambient environment/space conditions and uses the harvested energy to energize low-power electronics. An exemplary application is for wireless control (ON/OFF or dimming) of light fixtures. The energy harvesting circuitry transduces ambient light to electricity and uses this energy to charge an energy storage device as well as power a wireless transmitter which can be triggered based on user interaction with an ON/OFF or Dim+/Dim− element. The wireless light switch with energy harvesting circuitry is paired with a wireless receiver circuit which can be connected to a light fixture that is to be controlled by the wireless light switch.
