Oxygen concentrator

In a typical protection architecture for oxygen concentrators, high-energy surges and arcs are first diverted by GDT devices at the entry point, followed by MOV varistors for absorbing residual surge energy. TVS diodes provide fast transient clamping on supply and control lines. Low-capacitance ESD arrays protect sensitive signal interfaces and control logic from electrostatic events, while common-mode chokes filter EMI and high-frequency noise from cables and power rails. Proper placement and routing are crucial to maximizing suppression effectiveness and minimizing coupling into sensitive circuits.
