Energy storage is a valuable tool for balancing the grid and integrating more renewable energy. When energy demand is low and production of renewables is high, the excess energy can be stored for later use. When demand for energy or power is high and supply is low, the stored energy can be discharged. Due to the hourly, seasonal, and locational ...
The inductor subdues any output current fluctuations by changing its behavior between a load and a supply based on the SMPS current ripple. The inductor behaves like a load and stores energy to prevent ripples from producing excess current. It acts like a current supply when the ripple reduces the current value.
