Inquiries regarding Sinewave Inverter
Hi everybody,
I am a new comer in this forum. I have followed all the postings regarding sine wave inverter as I am interested in it. I am trying to make sine wave inverter of 600va. I made boosting section with sg3525 to convert 12v battery voltage to 350v dc with feedback. I used 100 kHz freq. with etd39 core. I also made battery charging section with separate ferrite core etd34 with 132 kHz freq. I want to make 350v dc rail to 230v AC with full bridge configuration and with pic 18f 1320/4550. While making this section, I am facing problem and invite suggestions regarding these.
In full bridge circuit, upper 2 N channel Mosfets require virtual ground and so keeping those 2 on for 10msec is difficult and hence if I keep the lower mosfet on and upper one pwm-ed with 50kHz, is there any problem?
Which driver is useful for driving mosfets in full bridge configuration?
I have made the sine table and will test soon and hence suggestions are invited urgently.
Hope to get suggestions from you all.
With thanks.
