Generator Controllers

High-Speed Generator ControllerIn addition to motor control products, Barber-Nichols Inc. (BNI) also offers high-speed generator controllers specifically tailored to turbo-generator systems.  Modern turbines typically operate at high speeds and can often operate across a wide speed range with changing input conditions.  For a generator system, this adds the complexity of variable output voltage and variable frequency.  In order to be useful, the generator output must be converted to DC or fixed frequency and fixed voltage AC.

BNI controllers utilize either active rectification to produce regulated DC power or passive rectification to produce unregulated DC.  The DC power can then be used directly, processed via DC-DC converter to a new DC voltage, or inverted to an AC output at customer specified voltage and frequency.   In addition, BNI generator controllers can provide over-speed protection, active speed regulation, or fail-safe braking during fault scenarios.

Generator Controller Features:

  • Flexible control and user interface options (see Motor Controllers)
  • Flexible commutation and phase angle control (see Motor Controllers)
  • Closed-loop turbine speed control via auxiliary load resistor
  • Fail-safe over-speed protection
  • Regulated DC output across wide range turbine input
  • Regulated AC output to customer specification
  • UL/IEEE grid tie certification available at customer request
  • 1W to 200 kW+ power range
