hello rvionics, thanks for the response,
the capacitor that i am using is 10,000uF, so is 0.01F.
how about the inductor? i am using a common mode choke with 5.7mH. will the problem come from the choke?Thanks.
Thanks rvionics,
btw, let the V output be 100 and the capacitor that i'm using is 0.01F, and i am applied a load resistor of 36ohm, so the output current i= 100/36=2.7778A and the switching frequency is 25kHz. Since the input voltage (48v)need to boost up to 100v hence the required duty cycle...
hi,
i am designing a two quadrant bidirectional dc-dc converter whereby at the input side, it is an input sources 48v (can be an energy storage unit:ultracapacitor) and at the output side it can connect to a dc motor drive with a regulated dc output voltage 100v.
i am using an inductor with...
inductor is the current storage device while capacitor is the voltage storage device. So, with appropriate calculation, you can get a suitable value for the converter filtering purpose.
you need to design an appropriate filter in order to cut off the ac and dc signal. at the first, select the suitable cut-off frequency and design on the filter afterward.
DC/DC Conveter
design a buck converter for the first.
and for the 2nd, what you need to filter out? voltage or current? you can apply capacitor or inductor to design on you filter circuit. btw, what the range of the input? or fix at 24v?
Using a PWM controller
using a transformer or a gate driver are better solutions ,since it provide isolation, and reduce the stress for some components.
dc/dc bosst converter simulink
hello, can someone email me the dc-dc converter with closed loop control?
wong_jennhwa@yahoo.com
thanks.
i have try hard to carried out the simulation process, but the output result cannot reach to the reference voltage...i am try to control it with PI controller...
