Abstract
In an electrical power generation unit with a prime mover having an output shaft rotating at a speed .omega. which determines an output power function having at each value of .omega. an output-power/.omega. slope M.sub.d, and a generator developing electrical power responsive to shaft rotation, a generator electrical impedance is selected to provide a generator output-power/.omega. slope M.sub.g to approximate the M.sub.d slope, so that .omega. can be controlled to maximize efficiency.
