Inrush current limiter
Abstract
A circuit arrangement for limiting turn-on current inrush and current rate of rise in dc-to-dc power converters is considered. A transistor control circuit is disposed between the input dc power source and the transistor oscillator circuit of the converter to provide a ramp of current thereto. The transistor control circuit functions as a time-variable current limiter initially while in the active region and as a saturated switch in the steady-state region. A feedback arrangement allows the saturation drive current to be provided from the converter at a lower voltage level than that which may be required from the dc power source to reduce dissipation and increase efficiency.
