Abstract: A DC/DC converter may be formed out of the combination of a first converter that is optimized to transfer energy from a voltage source to a load, and a second converter that receives a control signal derived from the load voltage to regulate the load voltage. The DC/DC converter may be configured as a sigma converter, a delta converter, or a sigma-delta converter. The mode of operation being selected according to the source voltage or the load voltage, either of which may vary over a wide range.

Abstract: A power conversion system with ripple injection includes an AC-DC conversion unit, a voltage regulation unit, at least one DC-DC conversion unit, at least one load, and a first control unit. The voltage regulation unit provides a DC link and receives one portion of an input power as an energy storage power. Each DC-DC conversion unit receives the other portion of the input power as an output power. The at least one load correspondingly receives the output power for being supplied power. The first control unit is coupled to the DC link, the at least one DC-DC conversion unit, and the at least one load. The first control unit controls the at least one DC-DC conversion unit to adjust a magnitude of a ripple of the output power to perform a ripple injection operation according to a magnitude of a ripple of the input power.

Abstract: An insulating piece for an electronic device is provided. The electronic device includes a first housing component and a second housing component. The first housing component includes at least one hook portion connected to the second housing component. The insulating piece includes a first covering portion, a second covering portion and at least one concave structure. The first and second covering portions extend in different directions. The concave structure is connected between the first and second covering portions. The concave structure and the second housing component form an accommodating space therebetween to accommodate the hook portion. The first and second covering portions cover inner sides of the first and second housing components respectively.

Abstract: A resonant conversion apparatus with extended hold-up time includes a resonant conversion unit, a time-extended unit, and a control unit. The resonant conversion unit includes a primary side, a transformer unit, and a secondary side. The time-extended unit includes a coil and a bridge arm assembly. When a switching frequency of the primary side is less than a critical frequency, the control unit controls the bridge arm assembly being switched on or switched off so that an output voltage of the resonant conversion apparatus is higher than a predetermined voltage within a hold-up time.
