dc-dc converter control

buongiorno a tutti sono un nuovo iscriitto
volevo chiederevi un aiuto
sto facendo una ricerca sul controllo dei dc-dc converter in modo tale da poter scegleire il più adatto ad ogni esigenza

sono risucito a trovare un elenco sommario delle possibili tipologie di controllo e vorrei sapere:
1)ne esistono altre oltre quelle che sto per elencarvi?
2)cosa piu importante,ho difficoltà a trovare descrizioni del loro funzionamento ,dei loro vnataggi e svantaggi,mi potete indicare dove poterlo fare passandomi magari il link piu adeguato per ogni tipologia?(nb:ho accesso a tutte le banche dati tipo ieee)

tipologie di controllo
- controllo a frequenza fissa
- controllo a frequenza variabile
- controll oa ton costante e varibile
- controllo a toff costnate e varibile
- controllo aisteretico
- controllo burst mode
- controllo di corrente a banda di isteresi

voltage mode
-average
feed forward

current mode
- peak
- average
- valley

-charge control

su voltage mode e current mode ho abbastnaza materiale(vi chiedo sol odi farmi sapere se esistono altre tipologie di vm e cm,sugli altir invece sono in alto mare)

vi ringrazio tutti in anticipo

Hello everyone I am a new partner
I wanted to ask help
I'm doing a research on the control of dc-dc converter so that you can choose the most suitable for every need

I have to find a summary checklist of possible types of control and I want to know:
1) there are others than those I am going to list them?
2) more importantly, I find it difficult to find descriptions of their operation, their advanteges and disadvantages, can you indicate where the link might be able to pass most appropriate for each type? (Nb: I have access to all databases like IEEE)
types of control
- Fixed frequency control
- Variable frequency drive control
- Control or ton constant variables
- Toff costnate and control variables

- Burst Mode Control
- Control of current-band hysteresis

voltage mode
-average
feed forward

current mode
- Peak
- Average
- Valley

I have a lot of material on voltage e current mode ,i need know information on other tecnique
thank you very much

Hi,
I think you can first study the scripts-Appl.Notes from Power Integrations, ST, Linear Technologies, National Semi & Maxim....
Of course; IEEE Trans-scripts are not bad, but mostly not so direct free readable publicated:-(
Other sites their are lot of books over switcher techniques, maybe some to read at "books.google.com" too?
K.

I'm workin in some direction but i would know if exist other control tecqnique over these
thnak you

voltage mode
hysteretic
adaptive on time control, you could say this is the same as constant on time



current mode
constant on time
constant off time
load feed forward


digital control

 

[atapy]

adaptative on time control is an extension of costant on time ,infact in the second you have a costant Ton ,in the first you have a TOn adapttive cycle for cycle

in any coases thank you very much
