SG3524 wiring circuit

The SG3524 is utilized solely as a pulse width modulator. The error amplifier is configured in a follower arrangement. As illustrated in Figure 10-7, the ACR output connects to PWM output pin 2, which serves as the control signal. The voltage VB is taken from the parallel single-ended output. When the output of the PWM pulse is closed, the motor stops. This method is also applicable for controlling DC motors and brushless electric motors. Since the winding current of a switched reluctance motor flows in only one direction, the PWM control integrated circuit is more suitable for this application, making it simpler to implement.

The SG3524 is a versatile integrated circuit designed for pulse width modulation (PWM) applications. In this configuration, it operates primarily as a PWM generator. The error amplifier within the SG3524 is configured as a voltage follower, which ensures that the output voltage closely tracks the input voltage. This arrangement is crucial for maintaining stability and accuracy in the PWM signal generation.

The ACR (Automatic Control Reference) output is connected to the second PWM output pin, which provides the control signal necessary for modulating the output. The voltage VB is derived from the parallel single-ended output, which allows for effective voltage monitoring and control. This setup is particularly useful in applications where precise control of the output voltage is required.

When the PWM signal is inactive or closed, the output signal ceases, resulting in the motor stopping. This feature is beneficial in applications that require immediate cessation of motor operation to prevent damage or ensure safety. The described PWM control method is not only applicable to DC motors but also extends to brushless electric motors, highlighting the versatility of the SG3524.

In the context of switched reluctance motors, the winding current flows in a single direction, making the PWM control IC an ideal choice. The simplicity of the design facilitates easier implementation in various applications, reducing the complexity typically associated with motor control systems. The SG3524's ability to manage PWM signals effectively makes it a valuable component in modern electronic motor control systems.Here, SG3524 only as a pulse width modulator uses.
