摘要：

This paper addresses a specific filter for integration into a motor drive system with an active front end. Three circuit configurations are investigated with focus on the high-frequency leakage current flowing out of a common grounded heat sink for two insulated-gate bipolar transistor modules. The motor drive system used in this experiment consists of a voltage-source pulsewidth modulation rectifier and inverter with the same carrier frequency as 14 kHz, together with an interior permanent magnet synchronous motor (IPM-SM) rated at 190 V and 5.5 kW. Experimental waveforms, along with putting an interpretation on their filtering performance, lead to the best filter configuration among the three.
