Jason outlines the concept of a dual conversion online Uninterruptible Power Supply (UPS) system. In its most basic form, this sees Alternating Current (AC) taken from the mains supply, converted to Direct Current (DC) through the rectifier, before the inverter reconverts back to AC.
In its most basic form, this sees Alternating Current (AC) taken from the mains supply, converted to Direct Current (DC) through the rectifier, before the inverter reconverts back to AC. In an online UPS configuration, this dual conversion (AC to DC, DC to AC) means the input and output are always independent of each other.
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.
A DC power supply converts alternating current (AC) from the mains power source into direct current (DC) that can be used to power electronic devices. There are several types of AC DC power supply, each with its own characteristics and applications. A linear power supply is the simplest type of AC DC power supply.
Uninterruptible Power Supplies (UPS) play a crucial role in ensuring a continuous and reliable power supply for critical electronic devices. When it comes to UPS systems, there are two primary types: DC UPS and AC UPS.
Most UPS systems are equipped with an inverter that can convert DC power stored in batteries to AC power during an outage. The inverter in a UPS is a crucial component that performs the conversion from DC to AC.
