Inverter three-phase overvoltage

Analysis of transient overvoltages and Self Protection Overvoltage

To mitigate this over-voltage problem, the IEEE std C62.92.2 has proposed certain effective grounding techniques for synchronous gen-erators. However, such existing methods require

Comparison of Overvoltage Regions Based on PWM Techniques

Excessive overvoltage caused by high-frequency ringing further degrades the motor winding insulation [7]. The magnitude of the overvoltage is affected by factors such as the
