Industry's 1st SPM™ for Switched Reluctance Motors offers 40% space-saving -
FCAS50SN60
Industry’s First Smart Power Module for Switched Reluctance Motors (SRM) Reduces Power Circuit Space by 40%
The FCAS50SN60 integrates one high-voltage IC (HVIC) and low-voltage IC (LVIC), IGBTs, fast recovery diodes and a thermistor into one Smart Power Module (SPM™). This device comes in an ultra-compact (44 mm X 26.8 mm) Mini-DIP package featuring Direct Bonding Copper (DBC) technology that significantly increases thermal performance. The FCAS50SN60 not only reduces power circuit space by up to 40% compared to typically used discrete solutions, it also enables designers to incorporate the controller into the SRM assembly. This module greatly reduces overall system size while simultaneously enhancing reliability.
Features and Benefits
- 600 V/50 A rating asymmetric bridge converter- Low-loss efficient IGBTs and FRDs optimized for SRM drive applications
- Single-phase IGBT asymmetric bridge converter features control ICs for gate driving and protection:
• High-side: control circuit Under Voltage (UV) protection (without fault signal output)
• Low-side: UV and short-circuit (SC) protection through external shunt resistor (with fault signal output)
- Built-in HVIC results in optocoupler-less interface and single-grounded power supply
- High-active input signal logic resolves the startup and shutdown sequence constraint between the control supply and control input providing fail-safe operation with direct connection between the SPM and a 3.3 V CPU or DSP eliminating an additional external sequence logic
- Isolation voltage rating of 2500 Vrms/min
- Very low leakage current due to ceramic heat sink and DBC substrate
- Package designed to satisfy the basic creepage and clearance spacing - UL certified No. E209204
Applications
- Switched reluctance motors (SRM) in applications such as vacuum cleaners
