    摘要: Method and circuit arrangement for generating a sinusoidal line AC voltage from a DC voltage. For generating a sinusoidal line AC voltage from a DC voltage, the DC voltage is converted into a square-wave voltage having voltage pulses whose durations are controlled in accordance with the variation of the sinusoidal line AC voltage to be generated. The square-wave voltage is transmitted via a high-frequency transformer. Subsequently, the transmitted voltage pulses are respectively tapped and filtered for a given chronological duration. A secondary side of the high-frequency transformer is respectively shorted during pulse pauses caused by the sinusoidal control of voltage pulse durations for a simultaneous constant applied pulse frequency. In these phases, energy is transmitted back to the source of the DC voltage via the high-frequency transformer. As a result, the circuit arrangement can also be employed as a charging circuit.

    摘要: A power supply unit for a computer system is proposed which has at least one data memory unit, which provides data specific to the power supply unit, for system controllers in the computer system. This achieves the object of offering the capability of ensuring that the power supply unit is not overloaded or underloaded, or that an appropriate message is output to the outside world, without having to explicitly know all the possible operational situations even in the development phase of the power supply unit.
