Power frequency UPS power supply is a long-standing power supply in the UPS industry, widely used in communication billing centers, communication base stations, bank branches, ATM machines, as well as network office environments in various industries such as securities, transportation, power, and industry. At present, the latest power frequency machines adopt the world’s most advanced […]

1、 Basic principles of UPS -UPS mainly consists of rectifiers, inverters, batteries, static switches, and other components. The rectifier converts AC power into DC power, which charges the battery and supplies the inverter. The inverter converts DC power back to AC power, providing stable power to the load. When the mains power is cut off,

UPS (Uninterruptible Power Supply) is a device used to protect electronic equipment from power outages, voltage fluctuations, and other electrical issues. It connects the battery to the power source to provide power to the equipment as a backup power source, in order to maintain the normal operation of the equipment in the event of a

For static UPS, it can be divided into two types according to its working mode: online and offline. However, both backup and online UPS have similar basic structures, except for certain differences in working mode and the quality of power supply to the load. Below, we will briefly explain the similarities and differences between online

In industrial applications, many loads have strict requirements for the output characteristics of inverters. In addition to variable frequency and adjustable voltage, the output voltage fundamental wave should be as large as possible and the harmonic content should be as small as possible. A square wave output inverter composed of thyristor components without self turn-off

Below is a detailed introduction to common UPS faults and their solutions. 1. When the mains power is available, UPS will issue a power outage alarm. Possible reasons: 1) The mains power input circuit breaker tripped. 2) Poor contact of input communication line. 3) The input voltage of the mains power is too high, too

A voltage regulator is a device designed to automatically maintain a constant voltage, and its main functions include the following aspects:

（1） Compensation principleThis compensating voltage regulator is based on the principle of electromagnetic induction to achieve stable voltage regulation. When the input voltage changes, the compensation winding inside the voltage regulator will automatically adjust the magnetic flux according to the voltage fluctuation. By changing the number of turns or current magnitude of the compensation winding,

The working principle of an inverter is to high-frequency switch DC power through electronic switching devices, forming a pulse width modulation (PWM) signal, and then convert the pulse signal into AC power through a filter. The basic structure of an inverter includes DC power supply, switching devices, control circuit, and output filter.
