Abstract

The invention relates to a power inverter, for example a direct d.c. converter, which applies the operating voltage thereof to the primary winding of a power transformer in pulse form, alternating between the positive and the negative direction. The secondary winding of the power transformer supplies a symmetric user, preferably a load that is connected to a double-way rectifier, wherein a parameter of the user process is adjusted and unadjusted parameters are limited by means of an additional digital signal that, independently of the adjustment device, effects the immediate switching off of the energy transmission. The adjustment and limiting occur due to the PWM signal generated according to the invention. The PWM signal is fed back to an observer, which generates a magnetization signal therefrom that controls the magnetizing current. Thus, a change in the control voltage is complied with immediately, which results in a flux shift. A correction value for the subsequent switch-on time of the PWM signal is calculated from the control voltage and the magnetizing signal by a symmetrizing device, such that the flux shift is terminated entirely or partially. The symmetrizing of the observer has the effect of symmetrizing the transformer, such that the magnetizing current of the transformer follows the generated magnetizing signal and can be limited while still in the linear range of the magnetizing of the transformer.
