TLDR
In this article, a control system for high-magnitude current pulses to a load, such as a magnetic pulse-forming work coil, at high-pulse rates by selectively charging a capacitor bank and then discharging the same through the load, the operation of the system taking place in a predetermined manner.Abstract:
A control system is disclosed for controlling the production of high-magnitude current pulses to a load, such as a magnetic pulse-forming work coil, at high-pulse rates by selectively charging a capacitor bank and then discharging the same through the load, the operation of the system taking place in a predetermined manner. A logic system automatically deactivates the control system in the event that the operation is other than in this predetermined manner, and antiringing circuitry eliminates ringing effects in the load circuit. A low-inductance, high-current damping resistor safely dissipates certain undesirable high-surge currents in the system to provide long component life and high-speed operation.read more

High voltage pulse generator
TL;DR: In this article, an inductive element is used to achieve a magnetic diode effect in the L-C inversion circuit to reduce component stress and improve efficiency, and a transformer-coupled floating gate drive circuit can be used as one method of providing local power conditioning and trigger timing for discharge of the energy storage capacitors.

Capacitor-type welding device and capacitor-type welding method
TL;DR: In this article, an economical capacitor-type welding device and a capacitor type welding method that can be made compact and reliably control a charging circuit without being affected by the inductance of a charging path is presented.
Patent
Methods and means for counting welding operations
TL;DR: In this paper, it was disclosed that a welder produces welds by discharging a capacitor bank through a stud to be welded, and that suitable diodes with sensing means suppress signals due to changes in charging currents in the capacitor bank.

Condenser welding system
TL;DR: In this article, Klemperer's work relates to condenser welding systems, and more particularly to those systems in which electrical energy is stored in a condenser and then discharged through a welding transformer to deliver welding current to a resistance welding load.
