IMPROVED EFFICIENCY PULSE FORMING NETWORK CHARGING SYSTEMS

摘要

A current feedback switch for the charging supply of a pulse forming network (PFN) is provided with regenerative feedback through a transformer T2 and a control transistor Q2 in order that base current be more efficiently provided to drive a main switching transistor Q1 to saturation. Turning-off the main switching transistor Q1 is facilitated by the transistor Q2 in series with the feedback transformer T2. In that manner current is more efficiently turned on and off to charge the PFN.
