Hey everybody, I've been sort of getting into pinball machines lately, and it's gotten me thinking that nearly all of an introductory mechanics class could be taught through the perspective of a pinball machine. Hooke's law for the launcher, acceleration components for the ball rolling...

I'm just doing it for funsies. It seemed like an interesting idea. I like building things, and I thought it would be an interesting challenge to see how high I could get the efficiency. I'm trying to see how valid they would be for grid tie PV systems, so I'll try something resistive and...

I'm using an mbed lpc1798 prototyping board, and used MATLAB to figure out the wait times. I'm using bootstrap circuits to drive the gates. The load will be just some dummy load for testing. Cascading multilevel inverters are supposedly more efficient, have less harmonic distortion, and produce...

Thanks Baluncore! So, I should be able to measure a higher peak current through the load than what's available from a panel, because each one has a cap in parallel. When a switch is turned "on", the panel and cap discharge (or provide current) at the same time and their currents add together...

I'm curious if anyone can validate the efficiency of a multilevel inverter. I've been thinking about them as a better solution for PV conversion. They seem to have many advantages, but when I look at it, a single phase output can seemingly only draw power from, on average, around half of the...
