Hai ,i am working on 200VA pure sine wave inverters.Actually my inverter efficiency affeted by odd number of voltage and current harmonics.how can reduce odd number harmonics magnitude and how can i design proper L & C to reduce harmonics in the load side.

Hi

My switching frequency is 10KHz and My true sine wave inverter blocks are
12V ,60AH Lead Acid Battery - MOSFET full bridge - 8V/270V,200VA,50HZ transformer 65uH secondary leakage inductance(1.5uf /305V AC, X2 cap connected across load for pure sinewave)- load

sinewave PWM by microcontroller

If you have any design note please kindly send to me
