Abstract
According to the present disclosure, an inrush current limiter comprises an input (190) for connection to a supply voltage, an output (202) for connection to a load, a current limiter circuit (102), a current bypass circuit (106), and a charge status circuit (104). During the initial charging of capacitors, the current limiter circuit (102) senses a large inrush current and limits the current to a predetermined quantity. The current bypass circuit (106) is switched off during the initial charging of the capacitors. When the capacitors are charged to substantially equal the input voltage, the current bypass circuit (106) is switched on to provide a low-resistance path for the supply current to pass through. In addition, the charge status circuit (104) operates to indicate the supply voltage.
