Schematics of halfbridge
ATX (AT) supplies with TL494, KA7500
ICs TL494 and KA7500 are equivalent. The letters of 494 can differ. Theese
supplies use bipolar junction transistors (BJT) of NPN type.

equivalents LPG899 and WT7520. Theese supplies use bipolar junction transistors
(BJT) of NPN type.
Schematics of forward topology
ATX supplies with UC3842, 3843, 3844, 3845 and other
ATX supplies using forward topology with single switch or double switch (half-controlled
bridge). Transistors are MOSFETs. Control IC's are UC3842, 3843, 3844, 3845 or
other IC's, which are a combo for boht supply and active PFC controll like
ML4824, FAN480X and ML4800.
