Lab testing of SMPS ?

Hi All,


I would really appreciate if some one could point me to what tests should i perform on a SMPS power supply in lab ? . Also what are the key parameters for SMPS .


Please do reply,

Regards,

Lab testing of SMPS ?

Hi,

Check the efficiency at different load current, Vout and Vin condition. Line and load transient response. Switching frequency, output ripple, reference voltage and other smps features/protection like OTP, UVP and OVP.

Cheers

Hey Thanks a lot for the information . I would apprecaite if you could be more specific on safety measurements

Thanks

User "gauravbishnoi" has wrongly made his reply as report.

It is here
hiiiiiii parameters are given as follows..... 1- you check i/p impedence of smps. 2- first you connect black & green wire of ATX connector then you give the power(220v ac) through power cable.And check condition of smps. 3. If fan is rotating then smps may be OK.
 

Re: What tests should i perform on a SMPS power supply in la

output recovery from thermal shutdown protection, overcurrent, short circuit, input brown out

power up and down at various load, line conditions, different input voltage ramp rates
