IGBTs dominate low-frequency high-power switching where MOSFET conduction loss would dominate. Most WPT coil inverters at 85–150 kHz use MOSFETs or wide bandgap devices — IGBTs appear in the dock AC/DC stage, pre-regulators, or legacy low-frequency IPT systems.

Know the boundary: above roughly 20–40 kHz, IGBT switching loss typically favors unipolar devices for new WPT inverter designs.

01Typical roles

Three-phase PFC or rectifier stages at line frequency modulation.
Very high power motor-drive shared infrastructure feeding DC bus to WPT.
Older kilohertz-range IPT installations still in field service.

02Coexistence with WPT inverter

IGBT front end plus MOSFET WPT inverter is a common partition. Bus stability and harmonic content from the IGBT stage must be validated with WPT full load. Gate drive and protection for IGBT modules differ — separate service manuals for field teams.

03Migration notes

Retrofit paths from IGBT IPT to SiC MOSFET WPT need new magnetics and EMC qualification.
Do not assume IGBT short-circuit rating transfers to high-frequency tank fault scenarios.
