<p>The converter has a filter capacitor (CF) across the load (2), and two switched alternate parallel supply paths (21,22). The first path (21) has a rectifier (210) and a current limiting resistor (R), and the second path has a second rectifier (220) with the only voltage drop that created by the potential drop over the rectifier components. A controller (24) with a reference voltage (Vref) operates the switch (23) to choose the supply path.</p> |
