LLC ze sterowaniem ładunkowym

W sumie fajnie wyszła ta symulacja, więc się dzielę. Dobrze widać ZVS itp. detale. "Przekładnię" reguluje się parametrem LIMIT_DELTA. Dynamika jest znacznie lepsza niż zwykłego konwertera LLC opartego na FM, a przy okazji jest to system pierwszego rzędu, znacznie łatwiejszy do skompensowania. Miłej zabawy. Jako zadanie domowe proponuję ciekawskim dorzeźbić pętlę sprzężenia zwrotnego. :-)

Pozdrawiam, Piotr

To mnie Janusz zastrzeliłeś, "u mnie działa". Masz aktualną wersję LT Spice XVII? Ja mam wersję z 22. sierpnia. W geście rozpaczy wrzucam to, co mam teraz na ekranie.

Pozdrawiam, Piotr

Mam chyba starą, mało tego używam bo generalnie wystarczą mi prostsze narzędzia. Z helpa wynika że mam LTspice IV v.4.23 Może da się rady przekonwertować na starą :) Bo chętnie bym 'obejrzał' a nawet zrobił taka przetwornice.
