The PWM Generator (2-Level) block generates pulses for carrier-based pulse width modulation (PWM) converters using two-level topology. The block can control switching devices (FETs, GTOs, or IGBTs) of three different converter types: single-phase half-bridge (1 arm), single-phase full-bridge (2 arms), or three-phase bridge (3 arms). MATLAB/SIMULINK MODEL; This section details the step by step development of Matlab/Simulink model for SVPWM. The Simulink model is shown in Fig. 6. Each block is further elaborated in Fig. 7. The Matlab code used to generate the switching pattern is also provided. Each sub-blocks of Fig. 6 is described in the following sub-section. Figure 6. PS-Simulink Converter: Converts the input physical signal to a Simulink ® signal. Controlled PWM Voltage: Generates the signal that approximates a pulse-width modulated motor input signal. H-Bridge: Drives the DC motor. DC Motor: Converts input electrical energy into mechanical motion. Current Sensor A PWM controlled four-quadrant Chopper is used to feed the DC motor. The Control subsystem includes the outer speed-control loop, the inner current-control loop, and the PWM generation. The total simulation time (t) is 4 seconds. At t = 1.5 seconds, the load torque increases.

Motor Control, Part 3: BLDC Speed Control Using PWM Video - MATLAB & Simulink Pulse-width modulation (PWM) is a common digital technique to control electrical power to a load using square wave pulses at some determined duty cycle. Proper control of pulse-width modulation ensures efficiency and accuracy in applications such as brushless motor control, solar power inverter control, and voltage regulation. Detailed information about the modulation algorithm, its Simulink® implementation, and the simulated case can be found in [1]. 1.

Proper control of pulse-width modulation ensures efficiency and accuracy in applications such as brushless motor control, solar power inverter control, and voltage regulation. This model shows how to use the Controlled PWM Voltage and H-Bridge blocks to control a motor. The converters are controlled in open loop with the PWM Generator blocks. The two circuits use the same DC voltage (Vdc = 400V), carrier frequency (1620 Hz) and modulation index (m = 0.8). In order to allow further signal processing, signals displayed on the Scope block are stored in a variable named ScopeDataForFFT, in structure with time format.
