How many watts is a small inverter?
You'll find a plenty of small and medium sized inverters in the market ranging from 100 to 500 watts, the same may be seen posted in this blog. Upgrading or converting such small or medium power inverters into massive high power inverter in the order of kvas may look quite a daunting and complex, but actually it's not.
What happens when a phase inverter reaches 0V?
When the output tube grids approach 0v and are driven positive, they no longer look like an infinite input impedance and begin drawing grid current. Because the phase inverter was not designed to deliver this grid current, the phase inverter sees a much heavier load when the output tubes distort.
How to upgrade a low power inverer circuit to a higher power?
The above explained ideas for upgrading a low power inverer circuit to a higher power version can be implemented to any desired level, simply by adding several MOSFETs in parallel. Adding MOSFETs in parallel is actually easier than adding BJT in parallel.
Why does a 12AT7 have a higher impedance than a phase inverter?
Because the phase inverter was not designed to deliver this grid current, the phase inverter sees a much heavier load when the output tubes distort. Because the 12AT7 has a lower internal impedance, it is better able to cope with the lowering impedance of the output tube grids when they distort.
Do phase inverters have high headroom?
Phase inverters typically have high headroom but (very likely) there will be interactions at the moment of powr stage overdrive due to grid clipping (possible PI clamping) and global negative feedback causing "error correcting" distortion in the voltage amp driver or voltage amp PI.
How do inverter topologies work?
All inverter topologies basically incorporate an oscillator frequency which is then amplified using power devices to high current levels before dumping into the step-up transformer for the final voltage boosting procedures.
