Hi Hgldr Sorry if my spec was not clearer but your understanding is pretty good The converter topology you proposed seems complicated . Why have you proposed this topology ? What are the advantages of this topology over say a simple push/pull converter Couls i use a Push/Pull converter...

Agreed, the input current spec is confusing The power is limited to 50W . Therefore with 25V input the current will be limited to 2A . The input current should be specified as 2A to 5A : 25V = 2A, 20V = 2.5A , 15V= 3.3A, 10V= 5A , 5V= 5A The DC/DC converter regulates the input current .

Hom Opera house . My spec is not confused . Think about it some more

It needs to regulate the input current 4.0A or 4.5A or 5.0 A The Vicor products regulate the output voltage

I want to design a 50W DC/DC converter . Spec Input voltage : 5-25V Isolation : Input isolated from Output Type : Isolated Boost Output Voltage : 28V - fixed by load connected to DC/DC converter output Input Current : 4.0A 4.5A or 5A - selected by the user .DC/DC converter sets input...

Hi Operahouse Thank you for your comments The input will be suppleid from a current source . The output is connected to a constant voltage load . The input /output voltage ratio of the isolator will be fixed ( 50% duty cycle + transformer ratio) .Therefore the input to the islator module...

The power specification has been changed from 50 to 500W. The input of the DC-DC Isolator vvoltage will be from a capacitor bank that will be charged by a current source . The output of the DC-DC Isolator will be connected to a constant voltage load . Therefore we should not to provide closed...

Hi OperaHouse You proposed Push/Pull . Why did you choose push/pull ? Would a Two transistor forward coverter be easier to control and have simpler magnetics ? Does the push pull have advantages over the forward converter for trhis application ?

Thanks OperaHouse . Good suggestion !!

I don't want to regulate the input or output voltage . I want to isolate input voltage only

Hi I want to design a DC-DC isolator with the following spoiec Input voltage 24-48V DC Input Current : 0-2A Power : Approx 50W Output voltage : 24-48V Output Current 0-2A Output Power :Approx 50W Efficiency : about 90% Isolation : Input isolated from Output Control : No control of...
