A Hệ thống UPS (Bộ lưu điện liên tục) is made up of several key components that work together to ensure a continuous power supply during power outages or disruptions. These components include the UPS rectifier, batteries, inverter, bypass switches, and other supporting systems.

Các UPS Rectifier is responsible for converting incoming AC (alternating current) power from the utility source into DC (direct current) power. It also plays a crucial role in charging the UPS batteries, ensuring that they are kept at full charge and ready for use when needed. In smaller systems, the rectifier and battery charger may be separate, while larger systems often combine these functions into one module. UPS rectifiers are designed to handle input voltage fluctuations, which allows the system to deal with overloads and surges without relying on the batteries.

UPS Batteries are a critical component of the system, storing electrical energy to power the connected equipment during an outage or voltage fluctuation. Typically, these batteries are either sealed lead-acid or lithium-ion. The number of batteries needed depends on the required DC voltage of the system. These batteries are often arranged in series within a string, meaning that if one battery fails, the entire string will be affected. Smaller UPS systems usually house the batteries inside the unit, while larger systems often feature external battery cabinets.

Các UPS Inverter converts DC power from the batteries back into AC power, supplying clean and stable electricity to the connected devices. This process smooths out electrical irregularities, such as voltage spikes, sags, and noise, ensuring the output is a pure sine wave. This conversion process is crucial for maintaining the integrity and stability of the power supplied to sensitive equipment.

Các Static Bypass Switch is another important component that ensures the uninterrupted supply of power. It monitors the quality of incoming utility power and, in the event of a power failure or anomaly, switches the load from the utility power to the inverter. While bypassing the UPS may not provide the same level of filtering and conditioning as an online double-conversion UPS, it ensures that equipment continues to operate during maintenance or repair of the UPS.

Các Bypass Switch allows for an alternative path for the electrical load, directly connecting it to the utility power. This feature is particularly useful during UPS maintenance, repairs, or in case of a fault. It provides flexibility in managing power sources without affecting the operation of connected devices.

A Monitoring and Control System is often included in Hệ thống UPS to provide real-time data about the status of the UPS and its connected load. This system can offer insights into battery health, voltage regulation, load balancing, and may include remote management capabilities for more efficient monitoring.

Cooling and Ventilation are essential to prevent overheating of the UPS system. As UPS systems generate heat during operation, they are equipped with fans or other cooling mechanisms to ensure proper heat dissipation and maintain optimal performance.

Many UPS systems also feature a Display Panel that provides users with critical information such as battery charge levels, input/output voltages, load levels, and system status. This user interface helps in maintaining awareness of the system’s performance and health.

Protective Devices such as surge suppressors and voltage regulators are incorporated to safeguard connected equipment from power spikes, surges, and fluctuations in voltage. These devices protect both the UPS system and the equipment it supports from potential electrical damage.

Together, these components form a cohesive UPS system that ensures reliable backup power, protects sensitive equipment from power disturbances, and maintains the stability and performance of electrical systems in the event of an outage.
