Definitions
- FIG. 1C shows a topological connection between the previously described master and slave half-bridge configurations in which a single DC power supply is shown. Furthermore, only a single set of voltage divider capacitors Cl and C2 are included.
- transformer L32 having two parallel windings N13 and N23.
- the primary windings of transformer L32 is connected to the common point of transistors Tl and T21 and capacitors Cll and C21. Assuming that the voltage of the winding Nil, connected in series with resistor R12, is positive with respect to the point sign, transistor Til must be ON. Although the magnetizing current of transformer L32 flowing in the winding N13 and series resistor
