PIC16F1827 HPWM Push-pull
U prilogu imas PDF od TI, na strani 5 je opisana klasicna 2-level modulacija i na strani 6 je opisana 3-level modulacija.

Uglavnom 2-level je kada od jednog PWM pomocu invertera pokreces pun most, dok za 3-level trebas imati jos jedan PWM modul koji radi inverznu logiku tj njemu je duty-ratio invertovan a ne izlazni signal, drugaciji je signal za drugu polovinu mosta, prost primer zelimo 70% izlaz, jedan PWM treba da se setuje na 70% duty-ratio ali drugi onda treba da se setuje na 30%, dakle treba dva PWM sa razlicitim duty (kada su oba na 50% nema diferencialnog izlaza na mostu), to je cela stvar.

Ako hoces od toga praviti nekakav sinus ili Class-D AMP, sve sto trebas je periodicno osvezavati ta dva PWM modula sa zeljenom vrednoscu dobijene iz neke sinus-lookup tablice ili dobijene sa A/D konvertera.
Ja sam to radio sa dsPIC i HIP drajverom i dobio sam fenomenalne rezultate, dsPIC ima dobar PWM i dobar A/D, radi bas bas dobro za nivo implementirane elektronike., recimo da je THD+N bolji od 0.1% u opsegu 0Hz-20kHz (PWM nosilac >150kHz), eto tako to radi u open-loop rezimu Smile
