The power harmonic components distribution study in the power circuit of a dynamic voltage restorer

Purpose. Investigation of the distribution harmonic power components in circuit a dynamic voltage restorer. Methodology. On basis differential equations restorer, search for relationship between mode parameters and elements is performed. obtained expressions, model regulator was created using methods mathematical modeling visual programming environment.. Findings. The that reflect restorer are obtained. As result with different composition current voltage, following features instantaneous revealed. Originality. It has been established presence harmonics acting transformer causes additional transformed windings. noted low-frequency LC filter dominate on capacitor, which connected parallel to winding, while level high-frequency caused by PWM modulation capacitor choke differ slightly. zero-frequency component storage corresponds tripled zero-time at output converter, due its operation three phases. This cannot be extended second third powers converter capacitor; these absent latter, energy exchange processes phases converter. Practical value. Using principle determining particular, elements, formulated.
