Uninterruptible power supplies (UPS) Bridge the power supply gap with Infineon''s total solutions for online and offline uninterruptible power supplies (UPS) systems.
Uninterruptible Power Supplies, or UPS for short, are indispensable in guaranteeing a consistent and dependable power supply for vital electronic devices. When delving into UPS systems, two main categories emerge: DC UPS and AC UPS.
AC power supply is a device that supplies alternating current (AC) power, and DC power supply is a device that supplies direct current (DC) power. The main difference between AC and DC power is the direction of electrons' flow.
The primary difference between AC UPS and DC UPS lies in the type of electrical current they use and the way they handle power during normal operation and outages. Here are the key distinctions between the two: Type of Power Input AC UPS: Accepts and uses AC as the input power source.
In an AC UPS, the incoming AC power is typically rectified to DC to charge a battery or a bank of batteries. During a power outage or disturbance, the stored DC power is then inverted back into AC power to provide a continuous and uninterrupted power supply to connected devices.
If your device starts with DC power, you will need a DC-DC power supply to generate regulated output voltage for electric and electronic applications. Unlike AC power, DC power cannot be changed from one voltage to another using a transformer.
A DC (Direct Current) power supply provides electricity flowing in one consistent direction. It’s typically sourced from batteries, solar panels, or through converting alternating current (AC) using an AC/DC converter.
