Title:
DC/DCアップ/ダウンコンバータの動作方法
Document Type and Number:
Japanese Patent JP2007518383
Kind Code:
A
Abstract:
A method for an up-down converter which is based on a buck converter during the current down-conversion phase (Phi2, Phi3 and Phi5, Phi6, respectively) of the coil (L1) supplies an output (B) with a relatively high output voltage (UB), where UB>Uin. The down-conversion phase of the coil current (IL1) comprises at least two different down-conversion phases (Phi2, Phi3 and Phi5, Phi6, respectively). A method for an up-down converter, which converter is based on a boost converter, supplies during the current up-conversion phase (Phi7, and Phi10, respectively) of the coil (L2) an output (D) which has a relatively low output voltage (UD) with power, where UD>Uin. The up-conversion phase of the coil current (IL2) comprises at least two different current reduction phases (Phi7, Phi8 and Phi10, Phi11, respectively).
