AC means ‘Alternating Current’, which means the current is constantly changing direction. In AC voltage, electric charges change direction periodically. It is the most common type of voltage used to transmit electrical energy across long distances. Generally, AC supplies power to homes and businesses.
Direct current (DC) voltage means the electric charges flow in only one direction. It is the type of voltage that batteries produce, and it is widely used to power small electronic devices like smartphones, laptops, and cameras.
What is the main difference between AC and DC voltage?
The major difference between AC and DC is the direction of the current flow. AC is an alternating current that periodically switches direction, while DC flows in one direction.
Another difference between AC and DC voltage is that AC voltage can increased or decreased to change the voltage levels using transformers. DC voltage cannot be as easily changed without the use of voltage regulators or power inverters.
How is AC and DC Power Used in A UPS System?
The the rectifier charges the battery and converts the incoming AC power to DC power.
