Power electronics busbars sit inside the commutation loop — between DC-link capacitors and switching modules — where every nanohenry of stray inductance counts. Three reference markets:
DC links and phase legs for renewable inverters rated toward 1500 VDC, with partial discharge controlled by layout and dielectric choice.
Low-inductance links from DC bus capacitors to IGBT stacks in VFDs, holding switching losses and voltage overshoot in check.
Low-profile distribution laminates feeding rectifiers and server cabinets, with controlled impedance and no wiring errors.
DC links are built with adjacent positive and negative planes to cancel loop inductance; the dielectric thickness between them is the main lever. Capacitor-to-module geometry is locked at DFM before any tooling is cut.
Blade and screw terminals are positioned to the exact pitch of your IGBT or SiC module pins, with weld zones sized for vibration life. Send the module part number and we align the tab pattern to it.
400 V class designs standard on PET; 800 V and higher move to Nomex or epoxy (DLF) with wider edge sealing. Read the low-inductance busbar design rules before release, and see inverter DC links for reference circuits.
