Robust systems often have several different power sources, and switches are implemented to separate the power supplies from each other to avoid damage. In most cases, multiple diodes are placed in the ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

An interesting analog design problem is the precision current source. Many good designs are available, but most are the three-wire types that can be used as a positive (see Figure 1) or a negative ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

You must provide ground fault protection for DC photovoltaic (PV) arrays. But you don’t have to, if they are ground- or pole-mounted PV arrays with not more than two source circuits isolated from ...
