Abstract

PURPOSE: To eliminate the DC irregular excitation of a transformer core of a cyclo converter by detecting the DC component current flowing the secondary winding of the transformer and controlling the firing phase of the respective thyristors form- ing a cyclo converter.
CONSTITUTION: This cyclo converter is composed of a current transformer CT, integrator 100, positive and negative P, N bridge conversion signal-synchronized switch Sd, holding element 10 and insensitive zone element 120. When the switch Sd is instantaneously turned ON at positive and negative bridge P, N switching time, the output Δid of the integrator 100 is applied to the element 110. This value Δid is the integrated value of the current during positive and negative bridge P, N energizing time and means DC component or level as the integrated value of the DC current of the secondary winding of the transformer up to the time point. Accordingly, when the cyclo converter is controlled by the value Δid, it can be controlled so that the DC component is always zero.
