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 mode for the tightest control and the most bandwidth. Provisions for applying different compensation schemes are included. The MSK4361 has good thermal conductivity of the MOSFET's due to isolated package design that allows direct heat sinking of the hybrid without insulators. The MSK4362 has +/-15V regulators integrated into the package to run the low power section of the hybrid, and/or for other external uses. See data sheet for regulator power dissipation calculation assistance. The evaluation board provides a platform from which to evaluate new designs with ample real estate to make changes and evaluate results. Evaluation early in the design phase reduces the likelihood instability, or other issues, from becoming a problem at the application PCB level. This application note is intended to be used in conjunction with the MSK4361 and MSK4362 data sheets, so please reference the data sheet for additional application information and specifications. AN010 1 Setup Use the standard 4mm banana jacks to interface with the assembly to connect to your power supply and motor assembly. The BNC connectors are provided to monitor the phase signals, clock sinc, E/A Mon., and I Mon. signals if desired.
