In the late 1990s I was working for a company that manufactures sub-systems for tramways, subways and light rail car manufacturers. One day my boss tells me that one of our inverters, a 5 kW DC to ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

A previous Idea for Design described a technique for protecting the “pass” transistor in a current-limiting circuit against excessive power dissipation (see “Fault-Protected Current Limiter Keeps Its ...
