@cmb I'm actually making the circuit in real life. My system is composed of many blocks. I'm analyzing each block ..As u know low voltage is too sensitive especially from the power prospect, unlike high voltage. Therefore, I must work practically and theoretically in parallel to know my losses...

berkeman sorry I have no right to provide the exact informations about the electromagnetic maybe you don t believe that there is EM with 4 HZ but it exists and I'm working with it in 4 Hz so my post has a sensing concept and I will build a management system that...

@jrmichler yes 4 Hz and collect 1 volt thank you but the problem does not exercise in the simulation software

My input source is electromagnetic so it produces 1Vrms and the fundamental frequency is 4HZ I simulate 1mA to 100mA because I m trying with µA but I m fairly to get a good result I m trying with mA I don t understand why the efficiency always a very week, however, the voltage multiplier use...

as you know as the transformer had many losses this is the problem so the voltage multiplier for the cold start time is better than the transformer just I will charge the capacitor 1.5 volt after that the semi-active boost rectifier will working

thank you but this is the challenges with this small amount of energy we will power a wireless sensor node

Baluncore electromagnetic energy harvesting my input it produces 1 volt with 4 Hz fundamental please how I can calculate the output power for this circuit? The impedance of the output capacitor will be some multiple of the impedance of one of the 47 uF capacitors at 4 Hz. That's some multiple...

Baluncore Thank you very much

hello, I did the simulation for the voltage multiplier in Vspace and I want to calculate the efficiency but the OUTPUT POWER is always negative. Do I need help? can I calculate the power losses of this sextupler voltage multiplier or it is very complicate to calculate it ?

no i i have' nt .net file for this circuit but how i can I input the file please ?

how please

hello I m Trying to simulate leakage current, say from a reverse bias diode I'm fairly how i can do it
