Parts list for 3000 Watts "modified sine" Power Inverter 12 Volts to 230 Volts
----------------------------------------------------------------------------------

R1,R2,R31,R32 = 470k

R8,R22 = 2,2 k
R9,R15,R27,R28,R39 = 1M
R14 = 47k
R17 = 3,3M
R20 = 0,001 (see construction plan)
R21,R45 ... R64 = 100 Ohm
R23,R40,R41 = 1k
R24 = 150 Ohm

R33 = 0,1 Ohm / 17 Watt for 3000 Watt output max.
R34,R42 = 150 k
R35 = 470 Ohm
R43 = 4,7k /   0,5 Watt
R25,R26 = 10 Ohm
R44,R45,R46,R47 = 22 Ohm

C1 = 47nF (no ceramic capacitor - frequency stability!)
C2 = obsolete
C3,C25 = 4,7uF
C4,C9,C11,C24,C26 = 0,1uF
C5 = 10000 uF
C6,C7,C10,C14,C23 = 220uF
C8,C12,C20,C22 = 100uF/16Volt
C13 = 220uF/35 V (max. 25 Volt through charge pump)
C15,C16 = 47uF
C17,C18 = 10nF
C19,C21 = 1nF

D1,D2,D3,D5,D6,D9,D14,D15,D16,D18,D20 = 1N 4148
D4 = ZPD 12

IC12,IC13 = LM741
IC3,IC4,IC5,IC6 = 1 x 4093
IC7,IC8 = 1 x 4013
IC11 = 7812

T1,T4 = BCY59 or BC547 (T1 affects the pulse width regulator and thus voltage regulation!)
T2,T3,T11 = BCY79 or BC556
T5,T8,T10 = BS 250 (IRF9Z24N)
T6,T7,T9,T12 = 2 N 7000 (IRFZ24N)
T13... T28 = 16 x IRF 3205

LED1 red, overload protection
LED2 yellow, load detection

Tr1 = 3000 VA
Tr2 = small transformer 1 VA, 230V/6V

F1 = 250 A (100 Amperes for 1000 Watts output)
F2 = 75 degree celsius switch off

Relay1 = 12 V coil, 2 contacts

1 heat sink 200mm x 100 mm
