  • Alternating current/direct current adaptor and self-adaptive voltage output method
    Patent number: 9160247
    Abstract: An alternating current (AC)/direct current (DC) adaptor is to be coupled electrically with an electronic device having an electrical property, and includes a DC/DC converter that receives a DC voltage signal and a control signal, and that adjusts the DC voltage signal according to the control signal to obtain an output DC voltage signal. A device discriminator receives the output DC voltage signal, and generates, according to the output DC voltage signal and the electrical property, a device indication signal set. A controller obtains a target value according to the device indication signal set, and outputs the control signal according to an initial value or the target value to control voltage value of the output DC voltage signal provided to the electronic device.

  • Controller for use in a resonant direct current/direct current converter
    Patent number: 7944715
    Abstract: A controller is adapted for controlling a switch of a resonant direct current/direct current converter, and includes: a pulse width modulation controlling unit for detecting an output voltage of the resonant direct current/direct current converter, and for generating a pulse width modulation signal according to the output voltage detected thereby; a fixed frequency signal generating unit for generating a fixed frequency signal; and a logic synthesizing unit for synthesizing the pulse width modulation signal and the fixed frequency signal so as to generate a driving signal that is adapted to drive the switch of the resonant direct current/direct current converter.
