Smart Power Module for SRM
Features
General Description
FCAS30DN60BB 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 SRM application especially for a
vacuum air cleaner. It combines optimized circuit 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 system. In addition the incorporated HVIC
facilitates the use of single-supply drive topology enabling the
FCAS30DN60BB to be driven by only one drive supply voltage
without negative bias.
•
600V-30A 2-phase asymmetric bridge IGBT converter for
SRM drive including control ICs for gate driving and protec-
tion
•
•
Single-grounded power supply due to built-in HVIC
Isolation rating of 1500Vrms/min.
Applications
•
2-phase SRM drives for home application vacuum cleaner.
