This stage has a high frequency transformer and the inverted AC drives its primary windings. This creates the up and down voltage at the output. If DC is required the output AC is converted to DC using a rectifier circuit using Silicon diodes or Schottky diodes fast recovery and minimum loss of current and low forward voltage drop . The rectified output DC is then filtered using
