Trace 1 in Figure 3 depicts the start-up of a 2.4-kW power supply with the inrush-current limiter and a slow-start circuit, which allows the separation of the inrush and the start-up processes. The ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

The high-current switch Q1, driver Q3, and the overcurrentsensing Q2 transistors with positive feedback form a bistable circuit suitable for this function (see the figure).

The current limiting circuit, though, is where things get interesting. Rather than use an op-amp, [DiodeGoneWild] chose a simple discrete transistor current-sense circuit.

Shown is a simple bidirectional current limiter. Figure 4 compares SiC JFETs with other technologies, using the channel resistance per unit of chip area as the figure of merit.

This paper proposes an analysis of the inrush load current and a design of the inrush current limiter circuit for a low-voltage DC (LVDC) distribution system. Due to the absence of a zero-crossing ...
