Abstract
Various embodiments relate to a load driver and a luminaire including the load driver. The load driver may include a voltage limiting circuit including a first polar capacitor and a second polar capacitor connected in inverse series, which are connected in parallel respectively with first and second current limiting elements, where the first and second current limiting elements limit the direction in which current flows so that current flows through different polar capacitors in positive and negative halves of a cycle of an alternating-current power supply.
