Modern hybrid electric vehicles (HEVs) like the fourth generation of Toyota Prius incorporate multiple planetary gears (PG) to interconnect various power components. Previous studies reported that increasing the number of planetary gears from one to two reduces energy consumption. However, these studies did not compare one PG and two PGs topologies at their optimal operation. Moreover, the size of the powertrain components are not the same and hence the source of reduction in energy consumption is not clear. This paper investigates the effect of the number of planetary gears on energy consumption under optimal operation of the powertrain components. The powertrains with one and two PGs are considered and an optimal simultaneous torque distribution and mode selection strategy is proposed. The proposed energy management strategy (EMS) optimally distributes torque demands amongst the power components whilst also controlling clutches (i.e., mode selection). Results show that increasing from one to two PGs reduces energy consumption by 4%.

In recent years, several new power module designs have emerged, principally driven by the severely challenging requirements for high power density and integration from the automotive industry. Indeed, electric and hybrid cars are the best example of technology innovation in the design of power modules. The Toyota Prius' fourth generation double-sided cooling power modules might be the most well-known example. Yet today many other module manufacturers are also proposing new designs that move away from conventional power module layers and technologies. In our presentation, we will start with market trends and illustrate how industrial applications still remain the biggest part of the power module market. We will then demonstrate that the automotive industry is leading in technological innovations in packaging, helping and accelerating the implementation of these new technologies thanks to high manufacturing volumes. We will detail these technology trends by providing real teardown and cost analysis of various power modules. We will explain how they are creating opportunities for some material suppliers, and at the same time, are transforming today's businesses for power packaging.
