Im building an ac/dc converter for a battery charger, it takes in 120V AC in and outputs 90V DC at 20A max. To further improve the output performance of the buck converter, i decided to build a pi filter containing 2 capacitors and an inductor..it is essentially used to filter harmonics at at...
I have read from several different sources that the duty ratio for a Cuk converter is
(Vo/Vin)=(-D/(1-D)
but several other sources say its:
(Vo/Vin)=(D/(1-D)
which is the correct one...i'm tad bit confused..
That is true, it is for a project I am doing in school..so I have no choice but to use it...since it is a cuk topology- it goes beyond the input voltage, and the conversion factor can be achieved for both inductive and resistive loads.
Hi, thanks for the advice..it shouldn't have more then 2 amps of flow through it, would you suggest something like this to be a suitable solution http://uk.farnell.com/multicomp/an-161-fc67203/circuit-breaker-1-6a/dp/698246
I have built an AC/AC cuk converter for an assignment I am doing. It works as such, I provide 50V AC in and I get an adjustable voltage out from 0V to 50V AC, depending on the duty cycle of the PWM that I gate to the MOSFETs. It is designed to supply a max of 1.5A rms to the load. I have...
Hi, once again thanks for the suggestions. I was pondering with an extremely simple idea of using a ad648 op-amp with a variable dc voltage on the inverting input and a fixed saw tooth waveform at say 4KHz at the non inverting input working as a comparator producing a form of PWM signals which...
Hi, thanks for the advice.
Yes, the gating wave forms are to be coordinated on both sides and I can confirm that simple on-off switching sequence would suffice. Unfortunately I am unable to determine how exactly should I implement the simple on-off switching sequence. Once again thank you for...
I am trying to build a specific AC-AC cuk converter for a project of mine. It involves the use of 4 MOSFETs configured in bi-directional switching states. I've included a picture of the schematic.
I am essentially building a solid state 'electronic' variac(variable autotransformer). I input 80v...
