Frank i tested the circuit by connecting the neutral of primary side of the transformer to the neutral of three capacitors and this was connected to the ground of DC which is also connected to the PSU 0V. I had 3A fuses placed in between the Rectifier's DC ouput and Inverters DC bus. These fuses...
Thankyou for your insights chuckey
The driver IR2109 comprises of an internal dead time to avoid both the high and low side Mosfets be switched on at the same time.
This maybe the cause of leakage inductance. What is your recommendation to solve this problem?

Thankyou for replying andre_teprom
I have connected 100W bulb on each phase (connected in Y configuration) on the secondary side of the transformer. Please correct me if i am wrong in assuming this as a balanced three phase load?
My design is for 500W. And if i am connecting the load directly...
I have designed a three phase pure sine wave inverter with spwm unipolar scheme. I am using a three phase rectifier to supply 200 Vdc on the dc bus of the inverter. Upon connecting a low pass LC filter i am able to get a 100Vrms pure sine wave across all three phase and the inverter is working...
