Abstract
One diode each is connected in antiparallel fashion to each load thyristor, said diode being a component of a commutation installation for the corresponding load thyristor. The commutation installation manifests an LC-series oscillatory circuit dimensioned for the specified load current and, for each load thyristor, a controllable commutation thyristor connected to a control circuit. Each commutation thyristor forms a closed circuit with the LC-series oscillatory circuit and its diode. One saturable choke each is connected in series with each thyristor and each diode. One RC-element each is connected in parallel with each thyristor and each diode, and saturation means are present for the chokes associated with the load thyristors. The inverter load may be the high voltage transformer of an x-ray generator.
