Single-Phase Half-Bridge Inverter Circuit

The single-phase half-bridge inverter circuit serves as a fundamental power electronics component that efficiently converts direct current (DC) into alternating current (AC). This circuit topology finds extensive applications across multiple domains including power electronics systems, electric vehicle powertrains, uninterruptible power supplies (UPS), and renewable energy conversion systems. In MATLAB/Simulink implementations, the half-bridge inverter typically utilizes two switching devices (such as IGBTs or MOSFETs) controlled by complementary pulse-width modulation (PWM) signals. The circuit operation involves generating alternating output voltage through proper switching sequences while maintaining dead-time protection to prevent shoot-through conditions. Key simulation aspects include DC bus voltage management, PWM carrier signal configuration, and output LC filter design for harmonic reduction. With the growing emphasis on renewable energy integration and advancements in simulation technologies like MATLAB, this component has gained significant popularity in both industrial applications and academic research. The MATLAB implementation allows for detailed analysis of switching patterns, harmonic distortion characteristics, and efficiency optimization through system-level simulations.
