Power Supply parts diagram: 1 IGBT power module, 2 rectifier transformer, 3 DC bus capacitors, 4 current shunt, 5 power supply, 6 EMI filter. 7 parts in 6 top-level items. — Power Supply parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	IGBT Power Module	2×	Active rectifier legs
2	Rectifier Transformer	1×	Isolation transformer matching mains voltage to the stack DC window of roughly 60–200 V.
3	DC Bus Capacitors	1×	Film capacitor bank that smooths rectifier ripple; low ripple current extends membrane life.
4	Current Shunt	1×	Precision shunt measuring stack current, the primary variable for production rate metering.
5	Power Supply	1×	Auxiliary 24 V rail
6	EMI Filter	1×	Line filter that keeps rectifier switching noise off the supply network.
