功率转换器的效率通常为标称高输出功率值而优化。然而，在高频应用中，例如宽带隙器件，在相对较低的功率输出下效率显著下降。由于大多数电源转换器大部分时间在相对较低的负载下运行，随着时间的推移，结果是显著的能源浪费。本文提出了一种创新的转换器设计方法来缓解这些问题。
Power converter efficiency is usually optimized for a nominal high output power value. However, in high frequency applications, such as with wide-band-gap devices, efficiency drops significantly at relatively low power outputs. Since most power converters operate most of the time at relatively low loads, the result is significant energy waste over time. This paper proposes an innovative converter design approach to mitigate such issues.
