  • Patent number: 11183994
    Abstract: A delay circuit is disclosed. The delay circuit is coupled to a relay switch that is contained in a power conversion device. When an electronic device having the power conversion device is operated in a sleep mode, the delay circuit applies a time delaying process to a power signal that is transmitted to the relay switch, such that a rising time of each of switch-on pulses contained by the power signal is delayed for a specific time. The specific time is set to be longer than a pulse width of each of power-on pulses contained by a power switching signal of the power conversion device. As such, when the electronic device is operated in the sleep mode, switching actions of the relay switch is properly controlled, thereby making the power conversion device not produce noise. Moreover, the service life of the relay unit is also extended.

  • Patent number: 11175691
    Abstract: A method for optimizing power of a ranging sequence includes counting at least one cycle of a first clock during a Crystal Oscillator (XO)-mode to generate a first cycle count. A second clock is activated at an end of the XO-mode. The first cycle count is converted into a fractional correction value by multiplying the first cycle count by a ratio of a second period of the second clock divided by a first period of the first clock. A first alignment of the first clock to the second clock is determined at a beginning of the XO-mode. A second alignment of the first clock to the second clock is determined at the end of the XO-mode. An adjusted cycle count is determined by summating the fractional correction value with a summation of the first alignment and the second alignment divided by the first period.

    Abstract: For grid-connected power converter control, a method estimates a d-axis grid voltage from a d-axis reference current modified with a d-axis current and a q-axis current modified with a filter inductive reactance. The method generates a q-axis current error from a direct current (DC) voltage input and a DC bus voltage. The method estimates an observer q-axis grid voltage from a q-axis voltage output. The q-axis grid voltage observer estimates the q-axis grid voltage in a direct/quadrature (dq) reference frame equivalent to an ABC to DQ reference frame transform. The method determines a d-axis voltage output as a function of a d-axis current error and a q-axis current modified with a filter inductive reactance. The method determines a q-axis voltage output as a sum of the q-axis current controller output and the observer q-axis grid voltage.
