Does the DC power supply provide direct current or alternating current?
The DC power supply provides direct current, and through the conversion device, it can also provide alternating current.
1. The DC power supply itself is a DC property, that is, the direction of the current does not change with time.
2. Because the DC voltage required by the equipment is high and low. Therefore, in order to meet the needs of different currents and voltages, the DC power supply can be transformed with power conversion technology to obtain the DC or AC power required by the equipment.
3. There are three types of ready-made power conversion equipment: DC to DC, DC to AC, and AC to DC.
4. DC to DC, mainly voltage conversion, such as 6V DC to 12V DC; DC to AC, usually converts DC of various voltages into a unified 220V AC, which is used for various AC 220V electrical appliances. Like solar inverter, it is the representative of this kind of DC to AC; AC to DC, like the mobile phone AC charger, is the charging power source of AC to DC.
