This paper presents a constant frequency hysteretic PWM controlled buck converter. In order to have good transient responses for input voltage and load current changes, a new PWM control method with inherent derivative characteristics is proposed. The proposed PWM controller consists of a comparator, ...
You’ll learn how to model a PWM-controlled buck converter for controlling the speed of a BLDC motor. In this video, we refer to a circuit diagram of a buck converter and try to model the same circuit using blocks from Simscape Electrical™. We a...
we’re able to adjust a constant DC voltage to different voltage levels. This helps us control a motor at varying speeds. The video demonstrates two common architectures for PWM control. In the first one, we use a buck converter along with a PWM generator to step...
