Abstract
A method for an up-down converter which is based on a buck converter during the current down-conversion phase (Φ, Φand Φ, Φ, respectively) of the coil (L) supplies an output (B) with a relatively high output voltage (U), where U>U. The down-conversion phase of the coil current (I) comprises at least two different down-conversion phases (Φ, Φand Φ, Φ, respectively). A method for an up-down converter, which converter is based on a boost converter, supplies during the current up-conversion phase (Φ, and Φ, respectively) of the coil (L) an output (D) which has a relatively low output voltage (U) with power, where U>U. The up-conversion phase of the coil current (I) comprises at least two different current reduction phases (Φ, Φand Φ, Φ, respectively).
