Hi
I am trying to program closed loop SPWM controller for an inverter using dsPIC33.
I get the feedback ac current and want to compare it with a sinusoidal reference current. So can anyone tell me how to generate 60Hz sinusoidal reference current in my dsPIC33. I only have the peak value of...
Re: boost converter
The output of Boost converter is not negative. The input and output of boost converter have the same polarity.
It is Buck-boost that has inverted output. And the reason is because of the topology. During ON state the indutor is in parallel with the source voltage. This...
Re: Duality theorem
Quantities having duality property

V=RI is equivalent to I=VG
If you substitute V with I, R with G and I with V you get same...
dspic33 linux
Thanks KST,
I know C30 complier full version is for free for 60 days and some functions will be disabled after that.
That is why I am thinking that after I wrote all the codes and everything and if it is not working after 60 days passed then all my work will be for nothing. So...
dspic c compiler
Hi,
I want to program a dsPIC33 chip using C. Does anyone know where I can find cheap C compiler to program the dsPIC chip. I know the microchip MPLAB C 30 compiler but it is very expensive 895.00 dollars.
So anyone has suggestions?
Greatly appriciate your help.
Regards,
abel
Re: a simple question
I think M1 is reverse biased since the base voltage polarity is 0. But M2 is forward biased. Therefore only M2 is conducting. And the current through M2 is 2mA wich should also be equal to Iin.
Eric.
According to your calcultation there are more charges in the capacitors than there was in the beginning. This violates charge conservation law.
The stored energy in the beginning cannot be the same as the stored final energy because work is done to move electric charges between points of...
I don't know how you come up to the conclusion that the charge will oscillate between the two capacitors.
What will happen is at steady state the voltage of the two capacitors should be equal because they are connected in parallel. For the voltage to be equal the charge stored in both...
Steady state voltage is V/2 if the iinital voltage is V
Initial Energy stored in C= (CV^2)/2
Final Energy stored in both Cs = (C(V/2)^2)/2+(C(V/2)^2)/2 = (CV^2)/4
Half of the energy Gone!!
In real circuit the energy will be dissipated in the wire resistance and/or the switching arc while...
Re: Power System Software
You can use PSIM to simulate power electronics circuits. It is very easy to use. You can download a demonstration version from the website https://www.powersimtech.com/ . It works fine if your circuit is not very big. If your circuit is too big you have to buy the...
digital vs analog bandwidth
Analog bandwidth is the maximum sinusoidal frequency of the analog signal the circuit works with.
But digital bandwidth of a circuit is different.
Digital bandwidth of a circuit is is less than analog bandwidth because digital signals are made of 1 and 0 values...
