A three-phase (single-phase) A-C power source operates the SP500 drive controller. The power source enters the controller’s input terminals and passes through three suppressors. These suppressors limit voltage transients within the maximum voltage rating of the diode module. The diode module rectifies the incoming A-C source to a constant D-C voltage. The internal power supply and a large D-C bus capacitor receive the D-C bus voltage. To provide the necessary voltage and current source required within the controller, the internal power supply is a D-C to D-C type. The large D-C bus capacitor filters the D-C voltage which then enters an insulated-gate bipolar transistor inverter bridge. The IGBT transforms the constant D-C voltage into a pulse-width modulated (PWM) voltage signal corresponding to the variable voltage and variable frequency source selected for the motor. Using a 4, 6, or 8 kHz carrier frequency, the IGBT inverter bridge is switched by the microcontroller.
