SCALE-2 technology improves current distribution by 20% for the new popular 100 x 140 mm dual IGBT and SiC power modules.
NUREMBERG, Germany, May 9, 2023 – (BUSINESS WIRE) – PCIM 2023 – Power Integrations (NASDAQ: POWI), a leader in gate driver technology for medium and high voltage inverters. SCALE-iFlex™ LT is introduced today. A series of NTC gate drivers for IGBT/SiC modules. The new gate drivers are designed for the new popular 100 x 140mm dual IGBT modules such as the Mitsubishi LV100 and Infineon XHP 2, as well as silicon carbide (SiC) options with blocking voltages up to 2300V. The SCALE-iFlex LT NTC driver provides data Negative Temperature Coefficient (NTC) (isolated power module temperature measurement), providing precise control of drive system temperature. This is especially important in systems with multiple modules connected in parallel, ensuring proper current distribution and greatly improving overall system reliability.

Torsten Schmidt, product marketing manager for Power Integrations, comments: “Renewable energy and rail system designers using SCALE-iFlex drives are already benefiting from improved system performance; the SCALE-iFlex approach handles concurrency so well that it eliminates 1 in 5 modules. with SCALE-iFlex. Loss of performance or derating. The addition of an isolated NTC output reduces hardware complexity (especially cables and connectors) and helps improve system visibility and overall performance.”
The SCALE-iFlex LT gate drivers are based on Power Integrations’ proven SCALE™-2 technology, which improves the accuracy of current sharing, thereby increasing the current carrying capacity of multiple parallel modules by up to 20%, allowing users to significantly increase semiconductor utilization. This is possible because the local control of each 2SMLT0220D MAG (Adaptive Gate Driver Module) provides precise control and switching for excellent current sharing. An advanced active clamp (AAC) is used to provide accurate surge protection.
For additional space savings, up to four MAG Drive Power Modules can be connected in parallel to one 2SILT1200T Isolated Master Control Unit (IMC), which can also be mounted on Power Modules due to its compact form factor. The gate drivers are fully compliant with IEC 61000-4-x (EMI), IEC-60068-2-x (environmental) and IEC-60068-2-x (mechanical) standards and are type tested – low voltage, high voltage, thermal cycling. – Reduces designer development time by 12-18 months. A full range of protection features are included with the option to use conformally coated components.
Samples of the new SCALE-iFlex LT NTC gate drivers are now available. Please contact your local sales representative for pricing.
