INVERTER GENERATOR AND PROCEDURE FOR CONTROL OF SUCH GENERATOR Russian patent published in 2011 - IPC H02M7/48 H02P9/04 H02K19/16 

FIELD: machine building.

SUBSTANCE: invention refers to inverter generator equipped with unit of generator with internal combustion engine drive wherein there is facilitated elimination on non-linear harmonic distortion to maximal allowed degree from output value of alternate current. According to the claimed invention there is a unit of the electric machine generator generating alternate current, a converter converting alternate current into direct one, an inverter transforming direct current into alternate one, a control unit of the inverter controlling key elements by means of POM-signal generated with usage of a reference sinusoidal signal and having a shape of wave of required output voltage, and also bearing signal. There are introduced a current metre for measuring alternate current supplied for electric loading, a device computing gain factors for calculation of gain factors Gn on base of measured current (where n = 2, 3, 4, 5, 6…m) of n-harmonics of the reference sinusoidal signal, and a regulator of the reference sinusoidal signal controlling this signal at a value of sum obtained on base of calculated gain factors Gn. According to the second version there is the unit of the generator driven form the internal combustion engine and generating alternate current, the converter connected to the unit of the generator and converting alternate current into direct one, the inverter connected to the converter and transforming direct current into alternate one and equipped with key elements for supply of electric loading, and the control unit of the inverter controlling the key elements by means of POM signal generated with usage of the reference sinusoidal signal. According to the claimed invention alternate current supplied for electric loading is measured; there are calculated gain factors Gn (where n=2, 3, 4, 5, 6…m) of n-harmonics of the reference sinusoidal signal, and the reference sinusoidal signal is regulated at value of sum obtained on base of calculated gain factors Gn.

EFFECT: conversion into alternate current of specified frequency by means of POM signal and control of reference sinusoidal signal for reliable elimination of constituents of non-linear harmonic distortion from signal of output voltage.
