TECHNICAL REPORT: CVEL-12-030 An Active Balancing Circuit for 3-Phase AC Motor Drivers
نویسندگان
چکیده
This report provides a summary of the design and testing of an active balancing circuit for three-phase AC motor drivers. The circuit actively compensates for the imbalances in the driver circuitry by driving the 0-volt ground on the circuit board relative to the common chassis of the load and the circuit board. The active balancing circuitry was able to reduce the common-mode current on the phase wires by as much as 10 dB in the 10 kHz – 20 MHz frequency range.
