AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are breaking technical barriers with faster circuit ...

Wireless power transfer (WPT) systems transmit electrical energy from a power source to a load without physical connectors or ...

ROHM has developed a 30 V N-channel metal-oxide semiconductor field-effect transistor (MOSFET) — AW2K21 — in a common-source ...

Based on the capacity of the capacitor and the final measured voltage of 907 VDC, roughly 36.2 Joule would have been collected, giving some idea of the power one could collect from a few ...

Your gadgets run on direct current, but the electricity in your home is alternating current. What’s up with that?

Bourns’ CRK1225 automotive-grade current sense resistor offers a higher power rating and wider resistance range.

The amount of V/R current drawn and V2/R power squandered in passive “pull-upping” depends on bus capacitance, pullup voltage, and duty cycle; and as Figure 1 shows, for fast-mode 400 kHz, V = 5 V, ...

Asia has a variety of high-voltage DC regulations. In Japan, mains power is only 100 V, meaning 1.5 kV and 2 kV DC power are already bracketed together, potentially meaning minimum fuss from a switch.
