-A transformer //**Tx**// is driven in a bipolar way ([[push-pull]],​ [[half-bridge]] or [[full-bridge]]). Two identical [[inductor|inductors]] //**L1**// and //**L2**// are connected across the secondary winding of //**Tx**//. Because of bipolarity, an alternating voltage is driven across the two inductors connected in series. The load //**R**// is connected between the central point of the inductors (similar to a regular centre-tap configuration) and the shorted output of the two diodes //**D1**// and //**D2**//. The low-pass filter can be implemented as the capacitor //**C**//, or as an additional output inductor (not shown).+A transformer //**Tx**// is driven in a bipolar way ([[push-pull]],​ [[half-bridge]] or [[full-bridge]]).
