Dual buck-boost DC/DC converter |
摘要 |
For a DC/DC converter with high dynamics and for high-voltage conditions, a provision is made that a capacitor series connection (2) of at least three capacitors (C1, C2, C3) is provided in the DC/DC converter (1), a first capacitor (C1) and middle third capacitor (C3) of the capacitor series connection (2) being part of a first inverting buck-boost converter (7) and a second capacitor (C2) and the middle third capacitor (C2) of the capacitor series connection (2) being part of a second inverting buck-boost converter (8), and that the first direct-current voltage (UIN) is applied to the capacitor series connection (2) and the second direct-current voltage (UOUT) is applied to the common third capacitor (C3) of the first and second inverting buck-boost converter (7, 8). |

1. A DC/DC converter for converting a first direct-current voltage into a second direct-current voltage, and vice versa, wherein a capacitor series connection of at least three capacitors is provided in the DC/DC converter, wherein a first capacitor and middle third capacitor of the capacitor series connection are part of a first inverting buck-boost converter and a second capacitor and the middle third capacitor of the capacitor series connection are part of a second inverting buck-boost converter, wherein the first direct-current voltage is applied to the capacitor series connection and the second direct-current voltage is applied at the common third capacitor of the first and second inverting buck-boost converter. |
