Abstract

PURPOSE:To obtain the desired sine wave output voltage and current easily as well as to contrive improvement of phase angle characteristics by a method wherein the phase angle is controlled by adding the bias signal, in proportion to the voltage generated on the commutation auxilliary circuit, to a phase control signal for every commutation. CONSTITUTION:The current controller 1 turns out a controlling output and it is inputted to an ignition angle controller 2 so as to bring the existing value list of the load current, flowing to the load of a converting device, to the desired current commanding value Isoll. An ignition angle controller 2 receives a phase angle controlling signal, which is a controlling output, generates the striking pulse of the desired phase, which is fed to the gate of each SCR constituting a converter. The output characteristics of a self-excited converter is symmetrically formed by adding the bias voltage VB corresponding to the increased component of the commutation capacitor voltage on the commutator auxiliary circuit to the controlling output which will be determined by the deviation between the current commanding value Isoll and the phase angle characteristics can be improved using the simple method abovementioned.
