  27. 2. Power Electronics and Drive Technologies in Japan • Requirement for high efficiency, fewer resources, high packaging density, and lower cost power electronics and drive systems. 2) Pursuit for high reliability of the whole drive system requires sensor-less control of not only speed sensor but also other sensors as the intrinsic solution. • Advancing SiC and GaN based power conversion technologies for high efficiency and high temperature operation. 4) Major factors for riding comfort are loudness, vibration, EMI noise and so on. These drive systems must control such factors within a permissible range for comfort of passengers. 5) In transportation applications, smooth acceleration and deceleration, sufficient starting torque, re-adhesion control against slips, and coasting operations are necessary.

  31. 3. Future Trends of Power Electronics and Drives Example for future standards architecture

  32. 3. Future Trends of Power Electronics and Drives Overhauled standardization landscape • *More requirements in group standards, less • requirements in product standards. • *Product standards use group standards as • reference document. • *Addition of further group standards based on • specific topics like: • EMC / EMF Grid connection Functional Safety ...... • *Movement towards topic experts, rather • product specialists ? Challenges Changes • Renewal of structures • Larger working groups • Achieving speed • Changing mindsets • Changed responsibility of subcommittees

  33. 3. Future Trends of Power Electronics and Drives The Japanese National Committee for IEC TC 22, 2013-09-27, 2014.1.30 IEC TC22 NWIP of bi-directionalgrid connected power converter Background *The bigtheme is the reduction of powerconsumption and diversification of power generation sources. *The 2nd motivation is a measure against a big blackout that could come just after a major disaster. Object *In order to optimize the power consumption of a home, it is necessary to combine a generator with a storage unit to control optimally. *For stable growth of a market, extendibility, and compatibility, energy conservation is important. Product certification based on new standard will advance the development.

  34. 3. Future Trends of Power Electronics and Drives Typical example of bi-directional grid connected power converter • Bi-directional GCPC is combined with multiple power sources for unified home power supply which provides electricity power to home appliances. Public mains Meter Bi-directional grid connected power converter Power source (PV,---) Distribution board DC/DC DC/AC Power source, battery(FEV,HEV,EV,….) Home appliances DC/DC DC-portinterface DC/AC: Grid side inverter DC/DC: Application side d.c. converter Power source: generator or storage DC-connection interface Finally, I think the world needs more power electronics, and power electronics is spreading to new applications to give a bright future.
