Title:
制御された多出力DC/DCコンバータ
Document Type and Number:
Japanese Patent JP2004518394
Kind Code:
A
Abstract:
A multi-output DC/DC converter (1;10;30;40;50;60), comprising inductive electrical energy storage means (L), switching means (S0-S7) and control means (6;9;31;41;51;61). The control means (6;9;31;41;51;61) are arranged for selectively operating the switching means (S0-S7) for transferring an amount of electrical energy from the energy storage means (L) to an output (A;B;C;D) of the DC/DC converter (1;10;30;40;50;60) providing an output voltage in accordance with a switching sequence based on comparing, by the control means (6;9;31;41;51;61) of the output voltage of each output (A;B;C;D) with an associated reference voltage. The control means (6;9;31;41;51;61) are arranged for operatively controlling the switching means (S0-S7) for each output (A;B;C;D) in accordance with an output individual switching cycle, wherein the switching sequence is comprised of the output individual switching cycles for transferring electrical energy to the outputs (A;B;C;D) of the multi-output DC/DC converter (1;10;30;40;50;60) in a predetermined order of priority.
