Overview#

Analysis of the requirements that we want to achieve

Power specifications:

  • Battery voltage: 40V

  • Maximum Power: 500W

  • Maximum output current: 10A Therefore, more or less, we have 10A current at the input, …

ADC for the resonant tank are limited to 0.5V (1Vpp)

Bypass capacitors must be used near to all the power supply pins.

add some common knowledge#

i.e. transformer model, how impedance move between primary and secondary

DSP#

The resolution that we can reach with a fft is equal to 1/time_window. E.g. we are sampling at 100Mhz a window of 500us (N=500us*100Mhz=50000), the minimum frequency that we can discriminate is 2kHz = 1/500us
