Power Module Solutions for Demanding Motor Control Systems

With heightened government regulations across the world, growing environmental concerns, and increasing global electricity consumption, the demand for energy efficient systems is at an all-time high. 

Electric motor-driven systems are the largest consumers of electricity, estimated to account for more than 40% of the world's consumption. Lighting systems, the next largest consumer of electricity, consume less than half that of motor systems.  Now more than ever, it is critical that motor system designs are as efficient and reliable as possible.

onsemi is driving energy efficiency innovations, providing a comprehensive portfolio of Smart Power Modules (SPM) that enable designers to develop high-performance, reliable, and highly efficient solutions for every motor control application.  These modules integrate gate drivers, power switches, and protection functions supporting systems from 20W to 7.5kW.

SPM 2 Series

Motion SPM® 2 series modules provide fully-featured, high-performance inverter output stages for AC induction, BLDC controller, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features: under-voltage lockouts, over-current shutdown, high accuracy, temperature sensing, and fault reporting.

SPM 3 Series

Motion SPM® 3 series modules provide a compact and high performance inverter solution for AC, BLDC controller, and PMSM motor drives in low-power consumer and industrial applications. Combining extensive on-module protections and gate drives matched to the low-loss IGBTs, system reliability is enhanced.

SPM 45 series

Motion SPM® 45 series modules were developed to provide a very compact and high performance inverter solution for AC, BLDC controller, and PMSM motor drives in low-power applications such as washing machines and industrial fans. It combines low-loss short-circuit rated IGBTs and optimized gate drivers in a fully isolated package to deliver a simple and robust design. The system reliability is further enhanced by the built-in NTC for temperature monitoring, integrated under-voltage lock-out function for both high and low side, and an overcurrent protection input.

SPM 5 Series

Motion SPM® 5 series modules are based on fast-recovery MOSFET (FRFET®) technology as a compact inverter solution for small power motor drive applications such as fans and pumps. These modules contains six FRFET MOSFETs, three half-bridge gate driver HVICs, temperature sensing, and three bootstrap diodes in a compact package, fully isolated and optimized for thermal performance. Electromagnetic interference (EMI) characteristics are optimized via tuned switching and reduced parasitic inductance. Employing MOSFETs, they provide much more ruggedness and a larger safe operating area (SOA) than IGBT-based power modules. These modules are ideal for compact and reliable inverter designs where assembly space is constrained.

SPM 55 Series

Motion SPM® 55 modules provide fully-featured, high-performance inverter output stages for AC Induction, BLDC controller, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, interlock function, over-current shutdown, thermal monitoring, and fault reporting. The built-in, high-speed HVIC requires only a single supply voltage and translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s robust short-circuit-rated IGBTs

SPM 7 Series

Motion SPM® 7 modules provide fully-featured, high-performance inverter output stages for smaller appliances such as fans and pumps. These modules integrate optimized gate drive of the built-in MOSFETs (FRFET® technology) to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, thermal monitoring, fault reporting, and interlock function. The built-in HVIC translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s internal MOSFETs.

SPM 8 Series

Targets compact motor control applications such as industrial fans, pumps, washing machines, and refrigerators. The SPM 8 series integrates 600V Field Stop trench IGBTs, stealth diodes with extended short circuit withstand time, and three (3) half-bridge gate driver IC's. Separate negative IGBT terminals are available for each phase to support the widest variety of control algorithms.
