This video explains about ev charger inside the section primary switching uc3235 and secondary level switching with tiny transformer and igbt based push and pull circuit with main transformer , constant storing current with reactor , then convert with double diode , finally arrive 48vdc. https://youtu.be/KSjuuw04wGk

This vidoe explains about signals which are ac signal, pulse width modulation and zero crossing . microcontroller should receive clock signals by crystal oscillator, smps switching ic (example top 252pn ) generates pwm signals, zero crossing measuring AC waveform and measuring AC waveform(50 hz). Here, we used multimeter to measure signals. https://youtu.be/-McMhbMpzIo
