Abstract
A downhole power generation system includes a generator that generates AC input power having a variable input voltage that varies based on a rotational rate of a turbine, which in turn is based on a variable flow rate of a fluid flow. An active rectifier converts the AC power having the variable input voltage to DC power having a constant output voltage. This may increase the range of usable input voltages and decrease a number of flow kits used in a downhole drilling assembly.
