A Comparative Study of Hybrid DC-DC Converters by Indirect Power

Hybrid converters are becoming popular in recent years for their high power density and high efficiency. This paper reviews and classifies hybrid converters from the perspective of the power processed by their components. The power processed by reactive components and transformer is calculated to illustrate how the power is processed "hybridly" by different components, which can help us to understand the operation principles. Component level parameters of example circuits are also provided to illustrate how hardware is affected by the amount of processed power, which explains why hybrid converters can achieve better performance.
