第二输入电压Vin2则主要是较低电压的直流电压,例如直流电压24V、直流电压12V、直流电压5V等,也就是,第二输入电压Vin2介于一低压电压区间,例如:DC3.3V~DC24V、或是DC5V~DC12V,设计者可以根据实际需求进行设置调整,在本发明中不做限制。
在其他实施例中,第一输入电压Vin1可以是需要符合安全规范高压隔离条件的输入电压,由于第一转换电路11中包括一第一变压器111,第一输入电压Vin1通过第一变压器111的转换,则可以符合安全规范高压隔离条件。而第二输入电压Vin2则可以是不需要符合安全规范高压隔离条件的输入电压,使用者可以根据实际需求进行调整、设计,在本发明中不做限制。

在本实施例中,多输入电压转换器1'与先前所述的实施例的多输入电压转换器1,差别在于多输入电压转换器1的第一转换电路11包括一第一开关元件113,而在本实施例中的多输入电压转换器1'的第一转换电路11包括一第四二极管元件113'。此外,多输入电压转换器1的输出电路13是包括一导通元件131,导通元件131为一开关元件。而在本实施例中,输出电路13则是包括一第六二极管131'。其他电路架构、电路运行以及相关元件大体是相同的,因此不在此赘述。
