Servo Amplifier parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Bare PCB Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2 Power MOSFET Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives.
3 Gate Driver IC Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT.
4 DC-Link Capacitor Large film or electrolytic capacitor across the DC bus of an inverter or converter that smooths voltage ripple and supplies switching current.
5 SMD Passive (R/C/L) 90× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
