Abstract
A regulating charging circuit for the pulse-forming network in a line-type pulse modulator, such as commonly found in pulsed radar systems. A charging inductor is the primary of a transformer, the secondary of which is open-circuited until the resonant charge of the pulsed-forming network reaches a predetermined voltage. At that time, a sensor generates a trigger enabling a solid state device, of the thyristor genera, to connect the secondary of the charging inductor/transformer to a step-up network, including a second transformer. The output of the step-up network is fed through a diode into the filter/storage capacitor of the high voltage power supply from which the charging inductor draws current. The unused charging conductor energy is thereby recovered and used to help recharge the filter/storage capacitor. The combination including the step-up network relieves the thyristor and control circuits from the requirement of controlling high voltages.
