The Semikron SKIIP 39AC066V4 M20 IGBT Module is a 3-phase bridge module designed to control power outputs and to switch energy from an AC source to a DC load. It utilizes an Insulated Gate Bipolar Transistor (IGBT) to provide high efficiency and low switching losses. Its unique connection of alternating positive and negative half bridges enables a wide range of applications like AC-DC conversion, DC-AC inverters, welders, UPS rectifiers, motor drives, etc. This module provides reliable, low-distortion, low-EMI operation, and features a series of overload protection such as over-voltage, over-current, and short-circuit protection. Additionally, the module support on-board logic for status monitoring and control.
