Abstract
The improvement of the structure is considered and the justification of the parameters of a multifunctional converter unit with a series connection of inverters for a combined electric power system of a local object with a photovoltaic battery is performed. There are obtained dependences of the amplitude of the ripple of the output current of the inverters, the error for fundamental harmonic, and the relation for determining the values of the inverter input voltage, reactor inductance, and PWM frequency according to the mains voltage and the maximum value of the inverter current, when it combines the functions of the active power filter. The single-channel control system structure with a slave current control loop with a common channel of current deviation for inverters has been improved. The external controller is determined by the operating mode: when working in parallel with the network, it is the current (voltage) controller of the photovoltaic battery, which under current conditions has less power; in the absence of energy production - the input voltage controller of one of the inverters; in standalone mode - load voltage controller.
