Simulations take into account real components (IGBT and Diode), the weight and volume of each converter were calculated based on datasheets. ; Hannan, M.A. 17 ( ) 18 () The results show that the converter follows the demand on power thanks to the good control. . 5 Princes Gate Court, Interesting variations of the simple design (pictured at right) found, for example, in the well-known Toyota Prius are the: The Toyota Hybrid System THS / Hybrid Synergy Drive has a single power-split device (incorporated as a single three-shaft planetary gearset) and can be classified as an Input-Split, since the power of the engine is split at the input to the transmission. It also offers control signals to the power conversion devices (inverters and DAB), which are generally employed in the integration of the NG system.
