Advances in power semiconductors and packaging lead to a compact integrated power stage for AC drives

Recent advances in semiconductor components and packaging (including areas like industrial modules, intelligent power modules, high-voltage ICs, and fully integrated power systems) offer motor control designers exciting new options for system integration that lead to lower-cost products with shorter design cycles. A POWIRTRAIN integrated power stage has been developed that offers an optimized combination of power semiconductors, gate driver, and system protections, all in an ultra-compact, plug and play drive system for AC induction motors. This paper discusses design philosophy and criteria, system block diagram and construction, and system specifications
