RESEARCHING SOLUTIONS OF DESIGNING INVERTERS FOR HIGH-SPEED ELECTRIC DRIVER SYSTEM USING PERMANENT MAGNET SYNCHRONOUS MOTOR

Abstract

Permanent Magnet Synchronous Motor (PMSM) uses permanent magnets,
so it has small mass, low moment of inertia for faster torque response, large
magnetic field strength, and reduced volume, so PMSM has high performance
reduces the cost and size of the inverter. In addition, the PMSM rotor does not
generate heat, which helps to dissipate heat in the motor better, some PMSMs
have added reluctance torque in the flux reduction control range, so they have a
wide power range. This paper focuses on researching solutions to design inverters
for high-speed electric driver system using PMSM motors, including the following
contents: Inverter structure, modulation solutions, voltage quality assessment,
analysis and selection. hardware selection, loss assessment and inverter
performance when working at high frequency.
