Description

Technical Field

[0002] A power rectifier is a device that converts AC power into DC power. It can be used for power supply devices and detecting radio signals. Rectifiers can be made of vacuum tubes, ignition tubes, solid-state silicon semiconductor diodes, mercury arcs, etc. On the contrary, a device that converts DC power into AC power is called an "inverter". In a standby UPS, it only needs to charge the battery and does not need to power the load. In a double conversion UPS, this device not only powers the inverter but also charges the battery, so it is called a rectifier / charger. A rectifier is a rectifying device, which is simply a device that converts AC power into DC power. It has two main functions: first, it converts AC power into DC power and supplies it to the load or inverter after filtering; second, it provides charging voltage to the battery, so it also acts as a charger.
