A source circuit, a power supply and an electric system. The source circuit includes at least one voltage source supplied from a mains circuit and used to provide at least one voltage for at least one device and at least one switch respectively connected to the at least one voltage source and controlled to be turned on according to a voltage of the mains circuit and/or at a timing after the mains circuit being applied corresponding to the device.

Source circuit and power supply and electric system

A method and apparatus of adjusting parameter for an electrical device. The method of adjusting parameter for an electrical device, the electrical device comprising a converter, the method including: calculating a performance evaluation parameter of the electrical device, when the converter using a parameter value table for running; adjusting at least one parameter value in the parameter value table of the converter according to an input parameter so as obtain the optimized performance evaluation parameter of the electrical device and use the adjusted parameter value table corresponding to the optimized performance evaluation parameter for running. Therefore, the self adapting parameter in the table will be enable to find the best performance for different input and load conditions and better performance of Harmonics will not limit the operation range.

Method and apparatus of adjusting parameter for electrical device

An isolated multiple-output power supply with a function of detecting the presence or absence of a load at an output port is disclosed. The power supply includes a first voltage source for providing a first voltage at a first node; a first diode having a cathode coupled to the first output port, and an anode coupled to the first node for receiving the first voltage; a second voltage source for providing a second voltage at a second node; a second diode having a cathode coupled to a second output port, and an anode coupled to the second node for receiving the second voltage; and a bridging circuit having two terminals respectively connected to the first and the second output ports. When the load is not present at the first output port, the bridging circuit pulls up an output voltage at the first output port to reverse bias the first diode.
