一种低频LC谐振逆变器架构及其在无刷直流电机驱动中的应用演示

This letter presents a low-frequency LC-resonant inverter architecture for brushless dc (BLDC) motor drives that eliminates the conventional 3-phase half-bridge structure and its inherent high-side switching challenges. The proposed topology employs only low-side power devices and utilizes an LC resonance mechanism to directly synthesize sinusoidal winding currents from square-wave inputs of the s...
