DC motor speed controller
M.S. Kennedy Corporation
isolated non-hermetic package. The hybrid is capable of 30 amps of output current and 75 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 (complementary) mode for the tightest control and
the most bandwidth. Provisions for applying different compensation schemes are included. The MSK 4462 has good
thermal conductivity of the MOSFET's due to isolated package design that allows direct heat sinking of the hybrid
without insulators.
