Such an important typology to know in a TN-C-S network, eliminating most of the earth leakage from the parasitic capacitance, removes the tingles on taps and other earthed equipment!
@@sandeepanand8661 Thank you to you Sandeep anand sir, for providing such a insight understanding of leakage current and common mode voltage in very easy way. Its going to help me in many ways 🙏.
sir i have a question... In recent transformerless pv inverter topologies, 2 out of 5 switches operate at 50hz and rest 3 operate at 10k hz frequency.Will there be discontinuity in conduction if switches(IGBT) with different frequencies occur in series in any mode of operation??

Thank you so much Sir. One thing Sir , you spoke about some paper towards the end. How can I obtain it?
Namaskar Sandeep anand sir, at time 25:39 if below two diodes are blocking voltages of Vdc/2, then upper diode will be blocking Vdc or Vdc/2 ?
Thanks for pointing out an oversight in the video. The blocking voltage of the top diode comes out to be Vdc/2.

What is the use of D5 diode in H5 inverter topology ?
D5 serves 2 key purposes
1. It ensures continuity of grid current during dead time of switches.
2. It allows non-unity power factor operation for H5.
thank you sir
Transformerless inverters are all junk.
