The pwm controller accepts the control signal and adjusts the duty cycle of the pwm signal according to the requirements. For higher currents you need additional cooling for t2 and increase c2 value. The control signal contains information on how much power has to be applied to the load.
This demonstrates the ability of transistors to use low voltage low current signal lines such as a parallel port or microcontroller io line to control higher voltage higher current devices like motors in this case pc fans.
It might be an analog or digital signal according to the design of the pwm controller. A simple circuit containing an inverter chip diodes trim pot and capacitor creates the variable duty cycle pwm. The control signal contains information on how much power has to be applied to the load. Get it as soon as mon jan 11.
