摘要： The DC/DC converter has a full bridge circuit, a transformer and a rectifying unit. The full bridge circuit is connected to a source DC voltage. The transformer is connected to full bridge circuit and receives the source DC. The transformer has a stationary winding and at least one selectable winding connected in series. If the source DC voltage is lower than a threshold value, the switch is turned on to increase the coupling ratio of the transformer. Therefore, the transformer converts the source DC to a DC voltage in a required voltage level.
摘要翻译： DC / DC转换器具有全桥电路，变压器和整流单元。全桥电路连接到源极直流电压。变压器连接到全桥电路并接收源DC。变压器具有静止绕组和串联连接的至少一个可选绕组。如果源极直流电压低于阈值，则开关导通，以增加变压器的耦合比。因此，变压器将源极DC转换为所需电压电平的直流电压。

摘要： A method for controlling a grid-connected power supply system having multiple power supply modules, a relay commonly connected to output terminals of the power supply modules and connected between the power supply modules and a mains power grid, and a controller controlling each power supply module and the relay. The method is performed by the controller after the grid-connected power supply system is started and has steps of determining if each power supply module outputs power, activating each power supply module and charging an energy storage capacitor of the power supply module, and activating the relay when the stored voltages of the energy storage capacitors of all the power supply modules are greater than a preset peak voltage of the mains power. Accordingly, required number of relays is reduced and the size of the system can thus be more compact.
摘要翻译：一种用于控制具有多个电源模块的并网电源系统的方法，通常连接到电源模块的输出端并连接在电源模块与主电源之间的继电器的控制器，以及控制每个电源模块和继电器。该方法在并网电源系统启动之后由控制器执行，并且具有确定每个电源模块是否输出电力的步骤，激活每个电源模块并对电源模块的储能电容器进行充电，并激活当所有电源模块的储能电容器的存储电压大于电源的预设峰值电压时继电。因此，所需数量的继电器减少，因此系统的尺寸可以更紧凑。
