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.

In solar PV systems, circuit breaker selection is something that is easily overlooked and time should be taken to select the correct solution. If the circuit breaker is not appropriate, it will cause ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...
