The ALTIVAR 58 (ATV58) family of adjustable frequency AC drive controllers is used for controlling three-phase asynchronous motors. This controller in from the range of: 1–75 hp (0.75–55 kW) constant torque (100 hp variable torque), 400/460 V, three-phase input. In this teardown, I am giving you an overview of how its built, non-destructively as the

Over the years I have collected a great deal of salvaged IGBT bricks from the different power electronics I have taken apart. It have primarily kept 50+ Ampere rated bricks, single or half-bridge modules and 3 phase modules without built-in protection. It mostly comes from UPS, motor drives, welders or x-ray generators.
