Abstract: An output-switch control system for an AC-DC power supply includes a push-button switch that has two triggers. The triggers correspond to different contacts of a detecting circuit, respectively. When the push-button switch is pressed to make the triggers and the contacts turn into a close-circuit state form an open-circuit state, the detecting circuit outputs a power-source-on signal, and when the push-button switch is pressed again, and either of the triggers and the contact turn into the close-circuit state form the open-circuit state, the detecting circuit outputs a power-source-off signal immediately. With the dual-transition signal certification at the contacts, safe output-switch control can be achieved, so as to provide a user with operational safety.

Abstract: Power line carriers (PLCs) are susceptible to transients and electromagnetic interference (EMI) on the power line. To address transients and EMI on the power line, an improved power PLC involves transmitting a signal over the power line using a controlled current source, where the current source is modulated by the signal. The current source output is designed to be independent of the voltage on the power line and the load, and thus, is less susceptible to transients and EMI on the power line. The system architecture of the improved PLC also allows for simple, predictable, and flexible termination. In an example implementation in the automotive industry, the improved high frequency PLC may provide a low cost replacement for existing communication interfaces. The improved PLC may consolidate system in-vehicle communication, reduce in-vehicle wiring, provide system flexibility, and decrease vehicle weight and system cost.
