Power supply for tungsten lamp
There is need for a regulated power supply for tungsten ribbon lamp
in the range from 0 to 20A.
I decided to make supply based on PWM (for TL494).
(eg, such http://nice.artip.ru/files/pwm-tl4941.gif)
But do not know how to do this scheme with current stabilization
(this is important for the lamp).
Early the lamp was fed from a computer power supply (without adjustment)
on the channel 5V. In this case, current consumption was about 18A.
The converter will be fed from the computer PS, but the channel 12B.
(current can take more than 20A)
