<p>The dc regulating unit circuit driving method is designed to increase the mean value of the output-voltage both for a drive with a fixed master pulse as well as for a drive with a fixed reset or clear pulse, such that switching difficulties as a result of discharge of the switching capacitors via the return charge branch can be avoided. The dc regulating unit circuit as in 2622351 is used. With drive using a stationary or fixed master pulse, the firing or initiation pulse for the master thyristor (n1) is given periodically; the oscillation thyristor (n4) is fired as near as possible to the firing time point of the master thyristor (n1), and the switching thyristor (n2) and the reverse oscillation thyristor (n3) are fired together such that their commons firing time point relative to the firing time point of the master thyristor, is delayed or retarded more and more.</p> |
