| 摘要 |
The invention provides for an AC-DC voltage conversion integrated circuit arrangement that integrates all control and protection circuits (52), as well as power transistors, into a single module (50). Passive components, such as the transformer (11) and capacitors (61-66), can comprise relatively very small components, as the switching frequency is in the KHz or MHz range and the arrangement includes one or more integrated switched mode power supply ICs (52) and can be provided in a wall outlet which allows for the provision of one of a plurality of DC voltages therefrom. <IMAGE> |
