Pwm Schaltplan

Pwm Schaltplan. As specified by intel (c.f. I couldn't find one in the library, so i wrote one.

The main thing is, the fan itself has to contain some smarts. It consists of a sawtooth waveform generator and a voltage comparator. Sg3525 is a voltage mode pwm controller integrated circuit.

25Khz, Acceptable Range 21Khz To 28Khz


An integrator block with an external reset input 3 55amp mosfet (with led indicator, the actual output is restricted by the pcb board and the connector), all 3 mosfet are equipped with heat sink to ensure sufficient heat dissipation. It has two pwm outputs both are an inversion of each.

It is a 16 pin integrated circuit. Die steuerung der drehzahl eines motors realisieren kann, gleicht in vielerlei hinsicht einem analogausgang. I think times the reason is the fan motor itself, which in itself is equipped with a lot of control electronics.

High Current Pwm Controller Based Around A 555 Timer.


Diese schaltung ist bereits mit bild 3 erklärt. This caused me that the engine depending on the pulse width was either on or off. The standard pwm frequency of 62500 hz was not suitable for braking the fan in its run.

Pwm Stands For Pulse Width Modulation And Ppm Stands For Pulse Position Modulation.

The fixed frequency of the sawtooth generator is set to a value that is large in comparison to the highest possible input signal frequency. It consists of a sawtooth waveform generator and a voltage comparator.
