IGBT module for driving AC motor is worth
30 discrete parts
ST Microelectronics has released an integrated power module
packed with control functions and IGBT devices for driving
AC Motors in home appliances such as refrigerator, washing
machine, Air-conditioners.
These modules available in the current range of 12 Amps
to 17 Amps and voltage rating of 600 V, enable advanced
current sensing and can be interfaced to embedded boards
directly to output ports of microcontroller chips. The controllers
inside the modules convert the microcontroller signals into
the high-power waveform to drive the motor. ST says these
modules can replace more than 30 discrete components.
The new modules are STGIPS10K60A, STGIPS14K60, STGIPL14K60,
and the STGIPS20K60. Each device has three 600V IGBT half
bridges with freewheeling diodes, control ICs, bootstrap
diode, temperature control and comparators to protect against
over-current and short-circuit faults. The STGIPL14K60 also
has internal amplifiers to support internal current-sensing
to control speed of the motor. To prevent high current related
damage to IGBTs, dead-time is inserted by these modules
through the internal circuitry. The smart-shutdown function
is also available in STGIPS14K60 and STGIPS20K60.
Package: Available in 25-lead or 38-lead molded SDIP packages
and use direct-bond copper (DBC) packaging to reduce heat
dissipation. The thermal resistance is rated at low 2.4°C/W.
Availability: Now in volumes
Price: Each $5.60 per 25K pieces
