So let's change the question. Let's suppose I want to make up a boost converter from scratch. How do I know it's a 150W, 200W, 300W,... 1000W converter? I was wondering if it's the limit current capacity of the inductor. Also, the output voltage is limited by the capacitor voltage limit. So for...
Let's say I want a DC DC converter to increase 12V to 48V, what information I have from the manufacturer that the converter is a 1500W or a 150W? Only the efficiency? The input voltage is the same!
For example this converter...
Hello,
I'd like to know what determines the output power of a DC-DC converter (let's say a buck converter)? Is it the input current, input voltage, the inductor current capacity...?
Hi,
I would like to know if there is any simulation program that allows me to know the current path through any circuit? Let's say to debug the circuit, to know what really happens during the simulation step by step.
Thanks.
Hey guys,
I want to know whether the nominal current of the inverter must be equal to the nominal current of the distributed generator connected to it.
Yes.. but there are some grid codes which state that the distributed generator must stay connected to the main utility even if the voltage at the point of common coupling drops to zero. That is why I am asking. So if it drops to zero, I do nothing and wait till it recover to the value before the...
and if the voltage falls to 0 V? Do I still have to inject reactive power to support the 0 V voltage? But the Q power is calculated by the voltage and it's zero...??
Hey guys
I'm sending this graph to show you the behavior of the PCC voltage during a sag event with and without reactive power injection. Grid codes establish that the distributed generator units should remain connect to the utility grid during voltage sag events and at the same time providing...
Hey guys
about fuel cell system connected to the grid, do you think that the fuel cell should deliver the exact energy to match the load, or would it be better to deliver the maximum power of the fuel cell to the load and the surplus power would go the grid? I say this because fuel cells use...
Hello
Some grid codes say that the distributed generation system should stay connected to the main utility during events of low voltage during a short period in accordance with each standard, this is called LVRT. At the same time the inverter should provide reactive power to the main...
What I still did not understand is why if I decrease the power injected by the pv panel, the frequency of the grid will also decrease. Let's say I have a pv panel at the roof of my house injecting power to the grid so that I can amortize the invoice amount a the end of the month. And if for some...
ok. But why in some grid codes is written that the power delivered by the distributed generation should decrease if there is a rise in frequency? Let's say for some reason the frequency is within the interval of 50.5<f<52 Hz, then it is said that the distributed generation should decrease its...
