    Abstract: A method for controlling a switching regulator includes defining a waiting time during which a trigger signal corresponding to a recirculation signal of the switching regulator is ignored holding a control switch in an open condition, and detecting a number of local valleys of the recirculation signal during the waiting time. In particular, defining the waiting time is performed for each switching cycle by adding a first value, which is determined on the basis of a load on the regulator, to a second variable value, which is proportional to the number valleys detected during the waiting time of the preceding switching cycle.

    Abstract: A DC/DC power transformer is provided which is an arrangement for direct transformation of high electric power from one DC voltage level to another DC voltage level without an intermediate AC voltage network. The DC voltage is today basically used for transmission of high electric power at long distances. The DC voltage levels for these transmissions are normally high. The DC/DC power transformer allows several DC voltage levels to be used in one and the same DC voltage network. The principle for this arrangement is that the valve windings (43, 45) from one or several converter transformers (47) are connected to two valve bridges, which generate opposing cyclically variating magnetic flows in the transformer cores (44). One of the valve bridges is operated as an inverter (42) and the other as a rectifier (46) and in this manner the power is transformed from one DC voltage level (U.sub.d1) to another (U.sub.d2). At high voltage levels the leakage inductances in the transformers will be high as a consequence of the insulation levels and therefore special arrangements must be made in order to commutate the magnetic energy from one phase of the transformer to another without creating great losses.

    Abstract: A switching regulator circuit for utilization with power supplies supplying a high DC output current including a plurality of control rectifiers and inductive reactors with sequential gating of the rectifiers at regular intervals for providing overlapped output current pulses from the reactors. An output circuit receives the rippled current comprised of the overlapped output current pulses for reducing the ripple therein. The output circuit includes a choke in series with the output which induces phase shift between the rippled current and the output current. A sensing winding associated with the choke eliminates the phase shift voltage for forming a feedback signal as an input to a control circuit. The control circuit utilizes the feedback signal to control the rate at which the rectifiers are gated sequentially.
