The current requirement is not top secret. please explain!
IanP,
are you kidding? 3 silicone diodes? what is that? how can you provide enough current?
I am thinking to design a voltage regulator from 3V to 1V, but I need high efficiency like LDO, anyone did LDO on 3V to 1V? regular linear regulator can do it, but efficiency is low(you lose 2V from 3V to 1V). I don't want to use DC-DC topology because it is noisy usually, this has to be low...
hello everyone,
I know Pout/Pin, what I don't know is that how do you take into account the heat dissipation by the swtching devices(such as H-bridge), these are major loss of power I believe. However, you can not simulate them, can you?
We have heard people claim inverter efficiency up to 99%, but really what is the definition of efficiency? if you account for the heat dissipation by the tansistors and passive components, there is no way you can simulate the efficiency and 99% is definitely can not be achieved. anyone has...
in a PLL design, you have PFD, meaning PD and FD, I have been doing PLL for over 10 years now, but never tried to simulate freq capture and phase capture seperately, sth came to my mind when I was reading a board message, that it is possible PLL will lock to certain frequency, but phase...
prathamesh,
looks like you 300VA inverter is like the microinverter from ENphase. what switch transistors do you use? IGBT or JFET or others for the bridge, which micro controller do you use? 8051?
What is your application for 100VA inverter?
-H
It starts to become meaningful discussion here.
prathamesh,
so you said your inverter is for single PV panel, what you doing is basically purchase ICs from various vendors, and design your own PCB, to make a inverter, do you have your own IC? I mean do you design your own IC in this inverter...
"integrated inverter" means the inverter is a single chip design, what are integrated into one chip in your case?
if I understand correctly, you use buck converter for MPPT, I am trying to fugure out how to do it, what is the idea behind, and any circuit? appreciate!

this is still called transformerless as the transformer is not used at output stage. true, your DC-DC has a transformer,but you use H-bridge.
question for you,prathamesh
did you design this as a integrated inverter? meaning integrate everything on chip except the transformer and cap?
what...
has anyone actually seen a fully integrated inverter? i.e. from DC-DC converter to controller, to H-Bridge? inductors can be off chip though?
or actually anyone is planning to do such an inverter, will it work? main concern is heat dissipation I guess.
hello,
I am doing a poll here, want to know what are the features do you want to have as a designer and customer in a new PV inverter design.
list yours here.
thanks

nobody wants a better PV inverter?
