PSD 112/12 is a twelve phase, three-level, unipolar Powersem Rectifier Module made by SemiKron. It is constructed with IGBTs, fast antiparallel diodes, a nominally balanced output and electrically insulated baseplate. The rectifier is also provided with a protection circuit that reduces power dissipation and increases reliability. The module is designed with a reverse blocking capability, allowing it to be used in AC-output applications. The design also helps to improve device thermal performance and EMI radiation. PSD 112/12 is ideal for high-power, high-frequency applications such as induction heating, motor and converter control, electronic ignition systems, welding, dc-dc conversion and uninterruptible power supplies (UPSs).
