How is current controlled in a capacitor type?

In the case of the capacitor type, the energy is regulated by adjusting the charged voltage.With a common capacitor type, since a thyristor is used to discharge energy, it fully discharges all stored energy.
With our capacitor type, while the power is regulated by adjusting the charged voltage, it is capable in performing constant current control, similar to MFDC, because an IGBT is used for an inverter control upon discharging.In addition, the remaining energy can be used for the next welding, which makes it a rational control method.
