Review of electrolytic capacitor-less PMSM drives [PDF]

open access: yesSCIENTIA SINICA Technologica, 2020
Electrolytic capacitor-less permanent magnet synchronous motor (PMSM) drives could improve the reliability and reduce the cost and volume of a drive system, which would be an important improvement over a conventional motor drive system. This has been successfully applied in aerospace, industry, and household applications. In this study, the development

Improved Modulation Strategy Based on Minimum Energy Storage Principle for Electrolytic-Capacitor-Less Six-Switch Converter

open access: yesApplied Sciences, 2021
An improved modulation strategy based on minimum energy storage for DC-link capacitance reduction in a six-switch AC-AC converter is proposed. The proposed modulation strategy enables the energy on the capacitor to accumulate and release twice each in a ...
