DESCRIPTION:
The MSK 4470 is a complete 3 Phase IGBT Bridge Brushless Motor Control System in a convenient isolated baseplate
package. The hybrid is capable of 10 amps of output current and 500 volts of DC bus voltage. It has the normal features
for protecting the bridge. Included is all the bridge drive circuitry, hall sensing circuitry, commutation circuitry and all the
current sensing and analog circuitry necessary for closed loop current mode (torque) control. When PWM'ing, the transis-
tors are modulated in locked anti-phase (complementary) mode for the tightest control and the most bandwidth. Provisions
for applying different compensation schemes are included. The MSK 4470 has good thermal conductivity of the IGBT's due
to isolated package design that allows direct heat sinking of the hybrid without insulators.
