TOP SWITCH

Posted by: sreekanthr on

Hi,

 

I am new to PI expert. I designed a circuit using Top Switch for the following Voltages

 

1. 24V @2A GND1

2. 24V@0.25A GND2

3. 15V@0.5A GND3

4. +12V@2A GND4

5. -12V@0.5A GND4

 

Feedback to TOP SWITCH is from +12V.

 

for reference i attachedPI expert file Also.

 

The circuit looks ok. and efficiency is about 92%.

 

Will it support for full loads on all supplies.

 

How reliable it is with full load.

 

What much be the components will get failure in future.

 

I want use this one in a VFD.

 

Plese clarify my doubts.

 

And suggest me the debugging procedure incase of failure.

 

regards

Sreekanth

All PIExpert designs are optimized based on the users specifications and should work fine under full load. Capacitors are usually known to have the shortest lifetime in a power supply. I would recommend performing an accelerated reliability/lifetime test on your power supply.

Thanks for the reply given.

What would be the minimum recommended load on feedback supply connected.

And can you recommend transformer manufacturers for this.
