A voltage quality module (VQM) function and a solar power generation function are integrated by sharing a single voltage converter (VC) within the electrical system of an automotive vehicle with an electric-start internal combustion engine. The cost of adding solar power generating capabilities to vehicles, the packaging complexities of the systems, and the number of added components are all decreased. The VC can be a DC-DC converter in a boost mode or a buck mode. A switching circuit selectably couples the VC between a main battery and an accessory bus or to between a solar panel and an auxiliary battery. A VC controller regulating a VC output using the main battery to stabilize an accessory bus voltage when in an engine crank mode and otherwise regulating the VC output to match an auxiliary battery voltage using the solar panel output. 通过在具有电启动的内燃发动机的机动车辆的电气系统内共享单个电压转换器(VC)来集成电压质量模块(VQM)功能和太阳能发电功能。减少了为车辆增加太阳能发电能力的成本、系统的封装复杂性、以及增加的部件数量。VC可以是在升压模式或降压模式下的DC-DC转换器。开关电路将VC选择性地连接在主电池和辅助总线之间、或者太阳能电池板和辅助电池之间。VC控制器在
