DESCRIPTION:
The MSK 4370 is a complete 3 Phase IGBT Bridge Brushless Motor Control System in an electrically isolated
hermetic 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 transistors are modulated in locked anti-phase mode for the tightest control and the most
bandwidth. Provisions for applying different compensation schemes are included. The MSK 4370 has good thermal
conductivity of the IGBT's due to isolated substrate/package design that allows direct heat sinking of the hybrid
without insulators. The anti-parallel commutation diodes are ultrafast recovery types for high efficiency/low switch-
ing losses.
