    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: An operation information processing section (11) in a central remote controller (5) processes operation information from operation setting buttons (8a,8b,8c), each of which is independent in function, transmits the operation information through a transmission line (6), and generates screen information based on the operation information collected through the transmission line (6), and display the screen information on a display unit (9). A management information processing section (12a) generates screen information based on operation information of the air conditioners (1,2) collected through the transmission line (6) and transmits the screen information to the remote monitor terminal (15) through a transmission line (13), and relays control information transmitted from the remote monitor terminal (15) through the transmission line (13), and transmits the control information to the air conditioners (1,2) through the transmission line (6).
