Solar inverters, storage converters, and charging modules do not use the same power devices. DUOX ELECTRONICS sources MOSFETs, IGBTs, power modules, and gate drivers by equipment type. Infineon, onsemi, ST, Mitsubishi, Fuji, and TI only illustrate the usual range. A quote still follows the full part number.
Shortages by equipment
An inquiry fits when an authorized lead time misses the ship date, a part is obsolete, the quantity is below a standard pack, or a qualified lot is required. Stock on hand, or a similar headline rating, is not an approved substitute.
| Equipment | Power parts that often go short |
|---|---|
| Solar inverters | MOSFETs, IGBTs, power modules, and isolated drivers, for production recovery, discontinued BOMs, and service stock |
| Energy storage | Low-voltage MOSFETs on the battery-side DC/DC; high-voltage MOSFETs, IGBTs, modules, and drivers on the grid-tied PCS |
| Charging modules | PFC and DC/DC kept apart. The approved switch and driver can differ by stage |
