Abstract
Control circuits (1) for controlling non-self-exciting converters (100) are provided with network circuits (11-16) for deriving control signals destined for the converters (100) for starting the converters (100) after zero-crossings of first signals that enter the converters (100). These control signals are derived from the first signals. The network circuits (11-16) may comprise serial connections of resistor circuits (14, 15) and main capacitors (13) and may comprise break-over-circuitry (11) for controlling switching elements (105) of the converters (100) via the control signals. The control circuits (1) may further comprise first regulator circuits (17-29) for, in dependence of the first signals, delaying the control signals to control an amount of power transferred, and may further comprise second regulator circuits (30, 31) for, in dependence of one or more load parameter signals, delaying the control signal to control an amount of power transferred.
