Description

one

The invention relates to the field of converter technology, in particular to methods for controlling parallel inverters.

Methods are known for controlling autonomous current inverters that ensure the output voltage is constant during load changes by setting the forward angle b while maintaining current continuity throughout the entire load range.

The disadvantage of this method is the need to ensure the continuity of the inverted current, which leads to an increase in the inductance of the input throttle, deterioration of the dynamic characteristics and weight and dimensions of the inverter.

The aim of the invention is to maintain the inverter output voltage unchanged when load changes in the mode of intermittent currents, to improve the dynamic characteristics of the inverter and to reduce the dimensions of the smoothing throttle.

To do this, in the discontinuous mode, in the period of the absence of an inverted current, the difference between the output and input voltages of the inverter is integrated to the specified advance angle, and after the specified angle of advance, the difference between the negative values of the output and input voltages of the inverter is integrated and at the instant that the integrated

the voltages are generated by the control pulses of the inverter valves.

FIG. 1 shows the line diagrams of the inverter voltages; in fig. 2 - block scheme of the device that implements the described method.

In the continuous current mode, the output voltage of the inverter is determined from the equality of the voltage-second areas I and II (see Fig. 1). This condition is obtained from the equality to zero of the half-period value of the voltage at the input choke of the inverter in the stationary mode. When the load decreases, the inverter may enter a discontinuous current mode, which leads to a change in the output voltage if the lead angle remains unchanged.

To keep the inverter output voltage unchanged when the load changes in intermittent mode, it is necessary to turn on the valves at the advance angle bpr determined from the equality

f (out -.) dt - f (t /, “, + and,) dt

A device that implements a change in the angle of control of an inverter with an arbitrary discontinuity of current contains an adjuster 1 of an inverter advance angle, a sensor of states of valves 2, a pulse distributor 3, form
