摘要： The invention relates to a method and a device for the production of two-channel or multi-channel pulse-width-modulated rectangular pulses. According to the invention, exactly one pulse is discharged within a period in each channel. The inception of a pulse in relation to the moment of inception is delayed by an actual dead time. The dead time is respectively kept constant for at least one period and a new value for the dead time is produced for a modulation of the pulse width and/or a new value is produced for the duration of the period and the actual dead time and/or the actual duration of the period is set at the beginning of the desired period according to the new value of the dead time and/or duration of the period.

摘要： A method and apparatus for generating an AC voltage in a system frequency range from a DC input voltage. Two opposite-pole, pulse-width modulated (PWM) rectangular pulses having a high switching rate are applied to the primary winding of a transformer. Every pulse is modulated to correspond to a half-wave of the AC voltage to be generated. On the secondary side of the transformer, the impulses of both PWM pulse trains are rectified to create a pulse train of a single polarity, the pulse width modulation of which corresponds to subsequent half-waves of the AC voltage to be generated. The pulse train so obtained is periodically commutated at double the frequency of the AC voltage to be generated so that a PWM signal representative of the AC output voltage is obtained with respect to amplitude, frequency, and polarity.
