String inverters
Boost and inverter-stage cores; loss at partial load matters as much as at rated power.

Magnetic Cores for Industrial PSU, Inverters and ESS
Industrial hardware is judged on what it does in a hot cabinet, at overload, five years in. The core selection follows the same logic.
Cabinet temperature and overload margin
- Wide temperature: the grade is chosen for the ambient inside the cabinet, not for the bench.
- Overload margin: check bias, loss and thermal margin against the permitted peak current, the overload duration and the protection trip conditions — the magnetic part is not expected to carry the full fault current.
- Lifecycle: second-source and long-life parts are quoted with the same data set, so an approved design stays approved.
Where each material fits
Industrial PSU
Transformer and choke cores for wide-input supplies, designed against the hold-up time, bus ripple and converter topology requirements placed on the magnetic component.
Energy storage
High-current inductors for bidirectional converters; bias behaviour decides the size.
