The capacitors are 22 microF. “Dyn” is a dynamo. The part to the left of the dotted line is a perfectly standard LED flashlight circuit. The right is the 'squeeze to charge/power lights' addition. And ...

In vehicle electrical systems, a high- to low-voltage DC/DC converter is a reversible electronic device that changes the DC from the vehicle’s high-voltage (400 V or 800 V) battery to a lower DC ...

Power stations have quickly become one of the more popular products we test. It’s easy to see why: They offer silent operation and easy to move to wherever you need power. Their rising popularity has ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

An SMU or Source Measurement Unit works a bit like a power supply, in that it can source current into a load and a bit like an electronic load, in that it can sink current from a power source. It ...
