Capacitor Discharge Circuit

Assembly

Storage capacitor and electronic switch that hold then suddenly release stored energy through the transformer primary to form each pulse. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

Capacitor Discharge Circuit parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Storage Capacitor 1× Energy store
2 Discharge Thyristor 1× SCR switch
3 Trigger Board 1× Small board generating the gate pulse that fires the thyristor on each timed cycle.
4 Power MOSFET 1× Charge switch
5 Bleed Resistor 1× High-value resistor that safely discharges the capacitor when the unit is switched off for servicing.
6 Bare PCB 1× Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
