TMS320F280270: Pure Sine Wave Inverter’s Reference Design

Dear experts,

Our customer has question below

//

I have read 800VA Pure Sine Wave Inverter’s Reference Design Application Report SLAA602A – June 2013 – Revised August 2017, it uses a second inverter mode to convert the low voltage DC power to AC, and then use a transformer to boost the voltage to 120/220 volts which is used in that reference design document.

We are actually interested in first inverter mode to convert low voltage DC power to a high voltage DC source, then to covert high DC source to an AC waveform using pulse width modulation. Do you have that kind of reference design application report?

Thank you.

Kind regards,
