Phase Shifted PWM Generator

Generates two synchronized PWM signals with configurable phase shift, frequency and duty ratio. Ideal for multi-phase power converters.

Phase Shifted PWM Generator

This block generates two synchronized Pulse Width Modulation (PWM) signals based on user-defined frequency, duty ratio and phase shift parameters. The second PWM signal is phase-shifted relative to the first signal

Features

• Configurable frequency (Hz)
• Adjustable duty ratio (0–1)
• Precise phase shift (0°–360°)
• Simulink-native integration
• Code generation compatible (Simulink Coder)

Applications

• Power electronics
• Motor drives
• Renewable energy inverters
• Embedded digital controllers

No additional toolboxes required.
