A multiport converter using a coupling inductor and a hybrid modulation technique was proposed for dual-voltage 12 V/48 V HV subsystems. The converter integrates two circuit topologies: an isolated DC/DC converter (DAB) and a non-isolated multi-phase DC/DC converter. This paper describes the integration method for the two circuit topologies. -

This report provides an overview of proposed circuit structure and control schemes for the PHV/EV on-board battery charger that uses a matrix converter. Power decoupling method which employs a small LC buffer is studied to suppress the single phase power fluctuation. The experimental result shows that the battery current ripple is reduced by 77.1%.

This paper presents a new electromagnetic torque converter (eMAT) for HEVs. The eMAT doubles as a high-efficiency torque converter and a traction motor for automatic transmissions of HEVs. eMAT prototype bench testing showed that the transmission efficiency in the vehicle moving-off mode can be improved compared to that for a conventional torque converter.

We propose a signal processing system to remove hybrid vehicle (HV) noise from a received AM radio signal. A replica of the HV noise is generated using the quadrature component of the received signal. The original HV noise is then canceled by subtracting the replica from the in-phase component.

Common-mode voltage generation at the DC input terminals of a full-bridge DC-DC converter is investigated in the FM radio band. The transient noise voltage with damped oscillation generated by transistor switching, acts as a noise source, and drives the common-mode voltage due to the impedance imbalance between two power lines.

The effect on the human body due to the leakage magnetic field from a magnetic coupling type wireless power transfer system was evaluated. It was found that the magnetic field strength and induced electric field in the body met the ICNIRP guidelines using a realistic charging scenario.

Recently, hybrid vehicles and electric vehicles have become widespread. These vehicles incorporate a large number of electronic devices and employ a high-voltage battery. Therefore, some devices are expected to be directly connected to the battery from the view point of power consumption. In this paper, we propose and demonstrate a high-voltage PLC to control electronic devices.
