  • Speed Error in PWM Fan Control Systems
    Brushless DC fan (BDC) speed can be varied using pulse-width modulation (PWM). The typical PWM control scheme inserts a power switch in series with the fan, as shown in Figure 1. In such applications, an increase in the active duty cycle causes a corresponding increase in fan speed (i.e., fan speed

  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    on or completely off. This efficient control methodology affords a very wide speed control range (typically 10% to 100% of full speed) because the fan motor is exposed to its full-rated voltage during the active portion of the PWM cycle. PWM control works with standard, two-wire Brushless DC (BDC) fans
  • MSK4225 Closed Loop Controller
    The MSK4225 is a MOSFET H bridge with internal gate drive and a PWM. generator, all in one convenient package. This configuration can be used to control a. variety of loads, such as a brushed DC motor or a voice coil. Because of the internal. PWM generator, all the user needs to do is provide
  • Intelligent Remote Positioner
    The excellent cost/performance ratio of the PIC16C5X makes it well suited as a low-cost proportional D.C. actuator controller. This application note depicts a design for a remote intelligent positioning system using a D.C. motor (up to 1/3 hp) run from 12V to 24V. The position accuracy is one
  • Software PID Control of an Inverted Pendulum Using the PIC16F684
    of three main parts: the base platform, the pendulum and the controller board. The base platform is a 3-point platform, 2 wheels (one of which is geared and attached to a DC motor) and an audio jack. When the DC motor is turned on, the base platform will rotate around in a circle with the center
