Abstract

This paper presents 10 kW grid connected photovoltaic inverter with high frequency transformer. This inverter system consist of DC/DC Converters, 2 high frequency transformers in parallel, diode full bridge rectifiers and 3 phase inverter. Proto Type inverter is manufactured and experimented. High frequency link DC-DC converter increases input DC voltage and supplies power to the inverter, which can energize directly the grid without LF step-up transformer. This system is lighter, more efficient and economical than the inverter with utility frequency transformer.

10kW高频变压器光伏并网逆变器的研制

本文介绍了一种10kw带高频变压器的光伏并网逆变器。该逆变系统由DC/DC变换器、2台并联高频变压器、二极管全桥整流器和三相逆变器组成。研制并试验了样机型逆变器。高频环节DC-DC变换器提高输入直流电压，为逆变器供电，无需低频升压变压器即可直接给电网供电。该系统比带工频变压器的逆变器更轻、更高效、更经济。
