PID Controller Design for UPS Three-Phase Inverters Considering Magnetic Coupling

Zhang, Yu; Li, Minying; Kang, Yong - In: Energies 7 (2014) 12, pp. 8036-8055

In three-phase inverters used in uninterruptible power supplies (UPSs), three-limb inductors and three-limb transformers are commonly used in consideration of cost and size. However, magnetic coupling exists between the three phases of the inverter, which can result in complex models. When...
