Abstract
The secondary winding is connected, via the series circuit of a capacitor and a second diode, to the charging capacitor which delivers the operating voltage. The centre point of the series circuit is connected to earth via a third diode. This enables energy to be recovered, in that the energy stored in the capacitor is delivered back to the charging capacitor during the inhibiting phase of the switching transistor.
