Smps with IR2153 for audio amplifier

[hien.t.nguyen]

My design an switching power supply use IR2153 + mofet(or IBGT) for audio amplifier

+/-63V,12A (unregular)
+/-15V,800mA for pre amplifier circuit
+12V,800mA for protect circuit,fan,...

size 12x12cm

 

[hien.t.nguyen]

Testing with load is resistor 30ohm(4.2A) + 1 lamp(0.6A) = 4.8A from B+ to B- ( total 126V = 63Vx2)

P = 126x4.8A = 604W not use fan in 2h
Heatsink for mosfet about 95 oC,if use small fan is power higher

Looks good
But it is not EMC
AC input socket mounting holes distance can be passed safety tests?

Thank all

I have an smps about 2.6kw
+/-100V,26A,use fan for heatsink

Hi Hien.t nguyen
greetings very many thanks for schematic my smps has no protection till now i will TRY this smps for SURE thanks for sharing schematic very kind of you
warm regards

Hi Hien.t.nguyen
greetings is this full schematic
1 source of CPR signal
2 overcurrent protection
3 voltage feedback

Thank your interested

PCB size of smps 2.6KW is 130x150mm,switching transformer use EE55

Dear Andrewlebon

1. Point CPR is over current protect (about 20A at pri)

3. My smps use IR2153 unregular for main voltage(+/-100V),not need voltage feedback

My smps has been over voltage protect,over current protect,over temperature protect.

Hi Andrewlebon

If you want to perfect protect,you can use this schematic

It is protect speaker and power amplifier,DC at output amplifier will be checked and if has incident(DC<>0.7V),power will not operation.
