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

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

However, electric vehicle batteries require a direct current supply for charging. Every EV, therefore, is outfitted with an inverter to convert AC to DC, which can in turn charge the EV’s battery.

Prototype and test result Figure 10 shows the TI universal AC-input 65W dual USB type-C port USB PD charger reference design with an integrated GaN power switch. Due to the simplified self-bias ...
