The active voltage regulation concept intends to substitute a traditional voltage regulation configuration by simplifying the overall topology. The easYgen internal controller regulates generator output voltage by sending a pulse width modulation (PWM) signal to the excitation module. The excitation module controls generator excitation and therefore generator output voltage. This topology eliminates the redundant voltage and current sensing from a traditional voltage regulator and also makes a feedforward control architecture at AVR level simplifying the cascaded PID control topology. For power input, EX-10 interfaces with any of the following excitation systems: Self/Shunt Excitation, Auxiliary winding/AREP Excitation and Permanent Magnet (PMG) Excitation systems to make it a standard yet versatile solution.
