摘要： A power conversion apparatus is disclosed in which AC sides of plural single-phase inverters (IB-INV, 2B-INV, 3B-INV, 2Ba-INV) that convert DC power of DC power sources (V 1B , V 2B , V 3B , V 2Ba ) to AC power are connected in series, and in which gradational output voltage control operation of an output voltage is carried out by using the sum of generated voltages from a predetermined combination selected from the plural single-phase inverters (IB-INV, 2B-INV, 3B-INV, 2Ba-INV). The apparatus is designed such that the plural DC power sources (V 1B , V 2B , V 3B , V 2Ba ) that serve as inputs of the respective single-phase inverters (IB-INV, 2B-INV, 3B-INV, 2Ba-INV) include a first DC power source (V 3B ) having the highest voltage, and another or other plural second DC power sources (V 1B , V 2B , V 2Ba ). Further, the first DC power source (V 3B ) is generated by a third DC power source (2) via a booster circuit (3). Additionally, an output pulse width of the single-phase inverter (3B-INV) that takes the first DC power source (V3 B ) as its input is adjusted so that the total quantity of power fluctuation due to charging and discharging of the respective second DC power sources (V 1B , V 2B , V 2Ba ) via the respective single-phase inverters (IB-INV, 2B-INV, 2Ba-INV) is reduced.

摘要翻译： 公开了一种电力转换装置，其中，对直流电源（V1B，V2B，V3B，V2Ba）的直流电力进行变换的多个单相逆变器（IB-INV，2B-INV，3B-INV，2Ba- 与交流电源串联连接，并且通过使用来自从多个单相逆变器（IB-INV，2B-INV）中选择的预定组合的产生电压的总和来执行输出电压的分级输出电压控制操作 ，3B-INV，2Ba-INV）。 该装置被设计为使得用作各个单相逆变器（IB-INV，2B-INV，3B-INV，2Ba-INV）的输入的多个DC电源（V1B，V2B，V3B，V2Ba） 具有最高电压的第一DC电源（V3B）以及另一个或其他多个第二DC电源（V1B，V2B，V2Ba）。 此外，第一DC电源（V3B）由第三DC电源（2）经由升压电路（3）产生。 另外，以第一直流电源（V3B）作为其输入的单相逆变器（3B-INV）的输出脉冲宽度被调整，使得由于各个第二直流电源（V3B）的充电和放电引起的功率波动的总量 经由各个单相逆变器（IB-INV，2B-INV，2Ba-INV）的电源（V1B，V2B，V2Ba）被减小。
