In this paper, HERIC transformerless inverter topologies with low leakage currents is proposed highly efficient and reliable inverter concept topology has been. concept (HERIC) topology has been discussed with Matlab simulation & also hardware implementation [1]. Index Terms—Common-mode. Brilliant ideas usually don’t need years of hard labor, or at least so it happens most of the time. For example, by implementing a switching trick.

The galvanic connection causes the stray capacitance between the PV arrays structure and the ground to produce a leakage current. To connect the solar panels with the electricity grid, direct current has to be transformed in alternating current ACwhich, in time and amplitude has a sine shape.


In this paper, a review of full bridge ehric with bipolar and unipolar scheme and half bridge topology carried out in regard leakage current. This site uses Akismet to reduce spam.

Unable to complete the topopogy because of changes made to the page. More or less, this is the logical schematic. To transform it into a sine shape it is then passed through an otpology.

Now, what Schmidt did first was realizing that losses in this circuit are caused by the return of current between the output inductor and the input capacitor. OK Reject Read More. Direct link to this comment: Other MathWorks country sites are not optimized for visits from your location.

He invented the trick back inand since he has been getting many awards for it. If the transformer is excluded from the system, it would increase the PV system efficiency and decrease the size of its installations, which will lead to a lower cost for the whole investment.

For example, by implementing a switching trick into a DC to AC current converter used in solar panels, Heribert Schmidt, an electrical engineer with a doctoratefrom the Fraunhofer Institute for Solar Energy Systems has managed to halve inverter losses, bringing the efficiency to 98 percent.
