Battery charger

Posted by: begajunos on

I wanted to design a battery charger for universal input voltage .

Specs are as follows
I/p voltage - 85-265VAC'
O/p voltage - 14.4V
Current - 10A.
Pls suggest pi device for this along with design inputs and schematics

Hi,

This being a new design, I recommend that you consider the TOPSwitch-HX or the TOPSWitch-JX family parts.

Given that this is a high power design, use of the e-SIP or the Y-package is recomended.

We have several design examples on our website and I suggest you review these designs:

We also provide a software called PIExpert which can be downloaded from our website free of charge. This software can help you with selection of components and transformer design. Please use the link below to download this software:

If you are new to power supply design, I strongly recommend that you review the following application notes before you start your design:

For the power level that you are trying to design for, other topologies such as the two switch forward may be a better option to consider though the component count will be higher. You may also review the design guide for our two switch forward integrated solution (HiperTFS) for which I have provided a link below:

As per the your recommendtaions whether the TOPSwitch-HX or the TOPSWitch-JX family parts will support 10A continuous current for charging the battery.
Iam looking @ constant current and constant voltage charging.
Pls give your feedback.Pls send the schematics if any for this design.

Hi,
Please refer DN-14.
There is examples for transistor or opamp based CC/CV and constant power applications.
Regards.

Hi guys,

I am posting my query in this post because I have similar application.
I want to build a battery charger with 60V output and 3 Amp charging current.
I have a microcontroller on secondary side to detect the current and voltage and drive optocoupler as per requirement.
Which family do the PI experts recommend for output power level of 180 - 200W?
I feel, two switch forward converter is a good choice in this case.
It is an adaptor kind of design.

Ankit Thakkar
