A300
A300 Street Car DC Propulsion System
Highlights
- Solid-State Control The A300 controls series field DC motors using power IGBTs (Insulated Gate Bipolar Transistors). These IGBTs control the speed and torque of the drive motor(s). Controlling a motor in this fashion yields high efficiencies with percentages in the mid to high 90’s. Using the IGBTs, the A300 controls motor and braking functions with a PWM (pulse width modulation) signal.
- Four-Quadrant Operation and Dynamic Braking The A300 is a four-quadrant motor controller, which allows it to be used to produce negative torque regardless of the drive motor’s rotational direction. This controller has the ability to provide dynamic braking, dissipating energy in outboard resistors as heat or returning the energy to the DC Supply.
