  • Patent number: 11929767
    Abstract: A transmission interface between at least a first module and a second module is proposed. The transmission interface includes at least two physical transmission mediums. Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated. The at least two physical transmission mediums include a first physical transmission medium arranged to carry a first multiplexed signal including a first IF signal and a reference clock signal. The first IF signal and the reference clock signal are at different frequencies.

  • Patent number: 11205956
    Abstract: A power converter with a common DC power source includes a DC power source and at least two power modules. Each of the power modules is coupled with each other and coupled to the DC power source. Each of the power module includes a coupled inductive component coupled to the DC power source, a DC output conversion unit coupled to the coupled inductive component, and a capacitor group having a coupling point. By using the coupled inductive component, it is to solve the problem of return current between the power modules caused by coupling multiple coupling points to each other.

  • Patent number: 10734835
    Abstract: A power bypass apparatus with a current-sharing function includes at least two bypass switch assemblies and a control unit. Each bypass switch assembly includes a controllable switch, a cooling unit, and a temperature detection unit. Each the temperature detection unit, correspondingly disposed to a heat-dissipating unit, detects a temperature value of the controllable switch to produce a temperature detection signal. The control unit receives the temperature detection signals and outputs at least two switch control signals to control at least one of the controllable switches or outputs at least two cooling unit control signals to control at least one of the cooling units, thus making currents flowing through the controllable switches identical. Accordingly, it is to increase overall efficiency of a power system and implement current-sharing function of the power system providing high power.

  • Patent number: 10554119
    Abstract: An inverter apparatus with overcurrent protection control includes a first terminal of a DC input terminal connected to an AC output terminal through a first switch element and a second switch element, and a second terminal of the DC input terminal connected to the AC output terminal through a fourth switch element and a third switch element. An intermediate potential terminal is connected to a fifth switch element and a sixth switch element, and connected to the AC output terminal through the fifth switch element and the second switch element, and connected to the AC output terminal through the sixth switch element and the third switch element. When the control unit determines that the inverter apparatus is in an overcurrent state, the control unit controls a sequence of turning off the inverter apparatus to be the second switch element, the first switch element, and the sixth switch element.
