Sinewave inverter prototype...

[waqasjamil]

hi ,
1)would #318 and #319 use with ir2110 for 310v to 220 v ?

 

[DeepOne]

will more simply do this with all new circuit (like #347) in contrast with remake #318 & #319 for ir2110 & 310V

 

[waqasjamil]

i think #318 and #319 has standard in programming (use sine tables ) etc

 

[pradeep.g.belchada]

is this inverter have battery charging facility

 

[DeepOne]

sorry, no battery charging in this circuit. May be later i do something on the base of mcu controlled arc welding device.

Hi DeepOne:
stm8s103f3 (TSSOP20) can complete the DC12V-AC220V Sinewave (PWM+SPWM) design?

 

[DeepOne]

Hi, Bbyl5009.
I have no complete design with stm8s103f3 (TSSOP20). 310VDC/220AC project is not complete because high level of the hindrances from working H-bridge obstructs output voltage measurements and overcurrent protection.
I think i know how solve this problem, but at present time i have no time for this

150W sinewave UPS for waterpump power backup

 

[DeepOne]

MCU with UC3843 as driver. not bad, as i see.

 

[naseerak]

what do you mean by not bad, as this would be a great achievement if it works satisfactorily..

 

[DeepOne]

I mean **3843 as mosfet driver is not worse than already mentioned scheme with three npn transistors and provide 5V supply for mcu and reliable current protection. And TL/UC/KA/etc 3843 is very cheap microcircuit.

 

[DeepOne]

HV modulator project, not ready.

 

[DeepOne]

worked version of that HV modulator.

 

[naseerak]

how are you detecting the overload

 

[DeepOne]

the mcu see low level on PINB.2 when inverter is in work and do necessary conclusion

 

[naseerak]

why don't you use TLP250 for high side switching..

 

[DeepOne]

npn+mosfet in output stage of HCPL is better than npn+pnp in TLP250.

 

[DeepOne]

full 12VDC_220AC ~600VA converter project, on the base of "HV modulator" ), not ready.

I was wondering did you end up getting the circuit in #161 working properly I like the idea of all discrete components and only one IC ?

thanks

 

[DeepOne]

as i remember that scheme is work, in principle, but more suitable to use mildly garbled signal with trapezoidal forms than this resemblance of the bridge scheme.
