MSK4370

ISO 9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. 4707 Dey Road Liverpool, N.Y. 13088 10 AMP, 500V, 3 PHASE IGBT BRUSHLESS MOTOR CONTROLLER 4370 (315) 701-6751 FEATURES: 500 Volt Motor Supply Voltage 10 Amp Output Switch Capability 100% Duty Cycle High Side Conduction Capable Shoot-Through/Cross Conduction Protection Hall Sensing and Commutation Circuitry on Board "Real" Four Quadrant Torque Control Capability Good Accuracy Around the Null Torque Point Isolated Package Design for High Voltage Isolation Plus Good Thermal Transfer 60°/ 120º Phasing Selectable MIL-PRF-38534 QUALIFIED 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/...
