Method for controlling a microinverter

摘要

The method involves defining a sinusoidal current (Sci) as a reference signal. A pulse signal (Spulse) is defined. A switch (A) of a group and another switch (D) of another group are switched for closing the switches at each pulse of the pulse signal. A current flowing in a closed circuit formed by the closed switches is measured. The closed switches are opened if the measured current is equal to a value of the sinusoidal current. The pulse signal is provided with two signals of a same frequency delivering the pulses with separate intervals out of phase with a half-period.
