ABSTRACT:
In a motor-generator set, the frequency of the AC generator outputted voltage is automatically adjusted by field winding regulation of the DC motor, through a closed loop in which a dual-slope converter is charged during a clock-defined time interval in accordance with a potentiometer setpoint, and the charging plus discharging period of the dual slope converter encompasses the period of the outputted voltage.
