Although the world’s first electric car was introduced as early as 1834, it was not until recently that electric vehicles (EVs) began to emerge in the mobility industry. A key to facilitating this change is the breakthrough in power electronics technology, which allows bidirectional electric power conversion between a direct current (dc)-voltage battery source and a variable-frequency alternating current (ac)-voltage load. This bidirectional function enables a regenerative braking technique to reduce energy consumption, and the use of robust and efficient ac machines. Consequently, EVs have gained a significant advantage over internal combustion engine (ICE) vehicles in terms of powertrain efficiency and have become a practical and attractive option to consumers. This trend is crucially important, as it accelerates the transformation to e-mobility, which reduces oil consumption and carbon dioxide emissions.

摘要

Although the world’s first electric car was introduced as early as 1834, it was not until recently that electric vehicles (EVs) began to emerge in the mobility industry. A key to facilitating this change is the breakthrough in power electronics technology, which allows bidirectional electric power conversion between a direct current (dc)-voltage battery source and a variable-frequency alternating current (ac)-voltage load. This bidirectional function enables a regenerative braking technique to reduce energy consumption, and the use of robust and efficient ac machines. Consequently, EVs have gained a significant advantage over internal combustion engine (ICE) vehicles in terms of powertrain efficiency and have become a practical and attractive option to consumers. This trend is crucially important, as it accelerates the transformation to e-mobility, which reduces oil consumption and carbon dioxide emissions.
