Fairchild offering a tool to select its
motion control devices
Fairchild Semiconductor has developed the Motion Control
Design Tool to assist in the selection of the optimum Fairchild
Motion-SPM device for their specific applications. This
tool addresses three-phase inverter sinusoidal modulation
for variable speed drive applications powering permanent
magnet synchronous motor (PMSM) and AC induction motors.
Part selection is based on a detailed entry of application
specific I/O information. The program output includes module
component losses, junction temperature increases, cooling
requirements and junction temperature ripple at the motor/output
frequency.
According to Fairchild:
The Motion Control Design Tool provides motor motion control
design engineers with:
A quick and accurate method for selecting the correct Fairchild
SPM device for their application
A simulation means for identifying their design's worst
case input and output conditions from a loss and temperature
rise aspect.
A delineation of the module's power component switching
and conduction losses for their specific application, enabling
them to quickly consider "what if" scenarios to
optimize the design.
Graphical presentation of internal component losses, junction
temperature rises and maximum allowable case temperature
as a function of output phase current and switching frequency.
Total module losses and heatsink/cooling requirements.
Fairchild Semiconductor says it recently developed a new
series of smart power modules (SPM), the SPM45H, that offers
high system efficiency while replacing up to 23 discrete
components.
Designed with system reliability in mind, the SPM45H series
features the integration of 15 fully tested components compared
to 23 discrete components, for 1.5kW motor designs. The
SPM45H come with built-in advanced NPT IGBTs. Advanced STEALTH
FRDs provide a good softness factor and low EMI characteristics.
