Abstract
A circuit arrangement which is provided with an up-converter (3) which comprises at least an inductive device (31), a switch (32), and a capacitive device (34) which in the operational state is periodically charged with a charging current in dependence on periodic switching of the switch. The switch is switched to the conducting state periodically during a substantially constant time t.sub.on. The circuit arrangement is provided with detection circuitry (I) for direct detection of the charging current. As a result, a load current which has a sinusoidal shape by good approximation is drawn from a connected AC voltage supply source by the circuit arrangement.
