The current-source inverter has an inherent defect: when the absolute value of the output voltage |u o | is less than the corresponding input voltage U ij N 2 /N 1j, the energy storage inductor L j is magnetized in the full switching cycle T s.Then the energy storage inductor current (i_{Lj}) keeps rising, which finally results in the magnetic saturation of L j and …
Power Inductors are used in variety of functions including differential mode filtering, output chokes and as the energy storage device in power supply topologies such a buck, boost, SEPIC and Cuk. The key parameters for a power inductor are the rated current (to ensure the part does not overheat), the saturation current (to ensure it will not ...
The stored energy in a coupled inductor can be used in multiple ways, both in isolated and non-isolated manners. The flexibility of utilization of stored energy makes the coupled inductor a versatile component. How the stored magnetic energy is utilized differentiates the functioning between the two topologies. Here, two examples are given.
