FCAS50SN60
Smart Power Module for SRM
Features
• Very low thermal resistance due to using DBC
• 600V-50A single-phase asymmetric bridge IGBT converter
for SRM drive including control ICs for gate driving and pro-
tection
• Divided negative dc-link terminals for inverter current sensing
applications
• Single-grounded power supply due to built-in HVIC
• Switching frequency of 2.2~8kHz
• Isolation rating of 2500Vrms/min.
Applications
• AC 200V ~ 242V single-phase SRM drives for home
application vacuum cleaner.
General Description
FCAS50SN60 is an advanced smart power module for SRM
drive that Fairchild has newly developed and designed to pro-
vide very compact and high performance SRM motor drives
mainly targeting low-power inverter-driven SRM application
especially for a vacuum air cleaner. It combines optimized cir-
cuit protection and drive matched to low-loss IGBTs. System
reliability is further enhanced by the integrated under-voltage
lock-out and short-circuit protection. The high speed built-in
HVIC provides opto-coupler-less IGBT gate driving capability
that further reduce the overall size of the inverter system
design. In addition the incorporated HVIC facilitates the use of
single-supply drive topology enabling the FCAS50SN60 to be
driven by only one drive supply voltage without negative bias.
Each phase current of inverter can be monitored separately due
to the divided negative dc terminals.
