Variable Frequency Pulse width modulator

Popis dijelova:

R1,R6,R11 = 10K C1 = 1000uF, 64V
R2,R9 = 1K8 C2 = 10nF, polyester
R3 = 100 ohm C3 = 100uF, 64V
R4,R8 = 1K C4 = 22nF
R5 = 22K C5 = 47uF, 35V
R7 = 1M
*R10 = 0.003 ohm D1,D2 = 1N4004
R12 = 3K9 U1 = LM7810, volt regulator
R13 = 100K U2 = LM324, Op-amp
R14 = 10 ohm/1 Watt Q1 = IRFP064, IRFZ44, etc. MOSFet
P1 = 20K (Frequency)
P2 = 10K (Duty C.)
P3 = 1K (Current L.)

Otpornik R10 je postavljen najviše zbog sigurnosnih razloga
