一种换流器输出功率调节方法运用于换流器中，换流器具有电容用以存储太阳能模块提供的直流电。于所述换流器输出功率调节方法中，首先至少转换太阳能模块提供的直流电成为交流电，判断交流电的功率是否大于功率值。当交流电的功率大于功率值时，换流器工作于连续模式。当交流电的功率不大于功率值时，换流器工作于不连续模式。于不连续模式中，以太阳能模块提供的直流电对电容充电，并判断电容的电压是否大于电压参考值。当电容的电压大于电压参考值时，太阳能模块与电容以脉冲形式提供的直流电转换成交流电。

An output power adjusting method is applied on an inverter. The inverter includes a capacitor to store a direct current provided by a solar energy module. In the adjusting method, first of all, the direct current at least provided by the solar energy module is converted to an alternating current. The method determines whether a power of the alternating current exceeds a power value. When the alternating current exceeds the power value, the inverter works in a continuous mode. When the alternating current does not exceed the power value, the inverter works in a discontinuous mode. In the discontinuous mode, the power provided by the solar energy module charges the capacitor. The method determines whether a voltage of the capacitor exceeds the voltage reference value. When the voltage of the capacitor exceeds the voltage reference value, the direct current provided by the solar energy module and the direct current in a pulse form provided by the capacitor is converted to the alternating current.
