Abstract: A method for controlling scan of slave devices, comprising: requesting, by a master, each slave to provide its device feature information; acquiring the device feature information provided by each slave in response to the request; sending, by a master, the acquired device feature information to the relevant slave to request the slave to confirm the information; registering the device feature information of the slave having sent an acknowledgement for the confirmation request as base information of the relevant slave; and repeating a scan process performing the above operations described above for each slave predefined N times.

Abstract: A apparatus provides a voltage clamp step-up boost converter that is capable of reducing voltage stress on a switch and a diode of the boost converter without using a dissipative snubber and that is capable of reducing a switching loss while maintaining a high input-to-output boost ratio.

Abstract: An apparatus provides a soft-switched voltage clamp tapped-inductor step-up boost converter that is capable of reducing voltage stress on a switch and a diode of the boost converter without using a dissipative snubber and that is capable of reducing a switching loss while maintaining a high input-to-output boost ratio.
