Patent ID: 8760001

Claim:
A supply circuit for an electrical supply of a vehicle, comprising: a battery configured to generate a battery supply voltage; a step-up converter configured to generate an intermediate voltage from the battery supply voltage; a temporary store configured to store electrical energy and supplied from the intermediate voltage, wherein the supply circuit is disposed inside a housing, and wherein the temporary store comprises a first electrical energy storage internal to the housing and a second electrical energy storage external to the housing; a first step-down converter configured to: generate a first consumer voltage from the intermediate voltage, the first consumer voltage for supplying a first consumer; and receive the intermediate voltage from the temporary store; a second step-down converter configured to: generate a second consumer voltage from the intermediate voltage, the second consumer voltage for supplying a second consumer; and receive the intermediate voltage from the temporary store; and a control circuit configured to control the step-up converter, the first step-down converter and the second step-down converter.
