Inverter board
The board was designed for the ETE ELN-inverter lab.
It receives 4 PWM signals to drive an H-Bridge. The bridge is followed by an LC-lowpass and a transformer.
A sigma-delta ADC reads the LC filter output and enables to adjust the output voltage.

Dead time
The dead time estimation for the H-Brige has been setimated by augmenting it an monitoring the power consumption of the system. The daead time was given by a counter clocked at 66 MHZ, but with a different number of bits for each measure. 3 | 860 4 | 170 5 | 70 6 | 70
