DC to DC power supply - has inductor as pre-inverter circuitry and drives inverter so that on-times of opposite transistors overlap

The power supply circuit includes a DC voltage source (S1) connected in series with an inductor (L2) across an inverter circuit including switching transistors (Q6, Q7, Q8, Q9) The switching transistors (Q6-Q9) are connected to provide paths through a primary winding (P) of a transformer (T). The secondary winding (S) is connected to a full wave rectifier (FWR) which supplies a power to load resistor in parallel with a filter capacitor (C2). The voltage across the load resistor (RL) is measured by a regulator (REG2) which provides switching inputs to the bases of the switching transistors (Q6-Q9). The switching pairs of transistors (Q6, Q7, Q8, Q9 are conducting during overlapping intervals. The (L2) acts to constrain a rapid increase in current, so eliminating the possibility of destroying the switching transistors even though they are conducting coincidentally.
