Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

The circuit in Figure 1 shows a PWM (pulse-width-modulated) ramp generator that you can use in low-cost switch-mode dc/dc power supplies. Its supply voltage can range from 5 to 35V dc, and you can set ...

[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only took ...

These editor-tested models are ideal for camping, tailgating, or powering tools when you’re too far from an outlet.

It hasn’t been that long since humans figured out how to create power grids that integrated multiple generators and consumers. Ever since AC won the battle of the currents, grid operators have had to ...

In the simplest of terms, an AC generator supplies power directly to a 120-volt circuit to run AC accessories throughout a boat, as well as charge the boat’s batteries (through an AC-to-­DC charger).
