Inverter - How to improve the output signal?

[unavezmasysale]

Hi,

This is the signal over the load on my inverter, I want to ask you how can I do to decrease the slope of the signal?




Any idea?

Thanks.

maybe a bigger core, Is that a Radio Shack unit?

Your waveform resembles the effect when series capacitors carry current pulses.

Simulation of modified sinewave inverter, using half-bridge.

Notice my load has sloped peaks.



I don't know that you are using this topology, but if capacitors are somewhere in the power loop, they might be causing the peaks to be sloped.

In that case it would help to increase the Farad values.

Dear SunnySkyguy and BradtheRad,

I had some problems with my scope. Everything is working fine now.

Many thanks.

Aha AC coupled input.
