Circulating currents in closed loop
WebMay 29, 2024 · The control is divided into two parts: (i) Voltage and current closed-loop controls in FBI and (ii) grid voltage and current with a phase locked loop (PLL) in MC. The FBI is performed as a voltage source to control the high frequency transformer voltage v ts and capacitor voltage v cb at the same time. Then, the high frequency transformer ... WebJun 23, 2004 · As part of the ocean conveyor belt, warm water from the tropical Atlantic moves poleward near the surface where it gives up some of its heat to the atmosphere. This process partially moderates the cold temperatures at higher latitudes. As the warm water gives up its heat it becomes more dense and sinks. This circulation loop is closed as …
