The UPS Trainer Demonstrator from AGN Enterprises is an educational power electronics training system designed for the practical study of Uninterruptible Power Supply circuits, operating stages, power conversion, battery backup, and output regulation. It provides students with an organized platform for understanding how a UPS maintains power to a connected load during an interruption in the main electrical supply.
The trainer demonstrates important functional sections such as the rectifier, battery charging circuit, inverter, control circuit, switching section, transformer, protection stages, and output section. Moreover, clearly arranged experimental sections help students follow the flow of electrical power through different stages of the system.
During normal operation, the power supply and charging circuits provide the required electrical conditions while maintaining the battery. However, when the mains supply fails, the battery and inverter section provide backup power to the connected load. Therefore, students can understand the relationship between AC-to-DC conversion, energy storage, and DC-to-AC conversion.
Students can use suitable measuring instruments at designated experimental points to analyze voltage and other permitted electrical parameters. Consequently, the demonstrator provides practical exposure to power electronics, inverter technology, battery charging, switching circuits, and backup-power concepts.
For additional information about electrical power and energy technologies, students can refer to the U.S. Department of Energy.
The UPS Trainer Demonstrator helps learners connect theoretical power-electronics concepts with an actual educational circuit arrangement. Furthermore, instructors can use the trainer to explain power flow, backup operation, inverter action, battery charging, and switching between operating conditions.
