The easy-to-install 42V power control system for Mild Hybrid Vehicle (MHV) was developed and introduced into market for the first time in the world, with (unique features such as) the high applicability to various types of vehicles (and other areas) as described below. The MG (motor/generator) to start the engine occupies the same location as the conventional alternator. It is driven by belt. The inverter unit uses the newly developed ellipse-type aluminum capacitor, and the size is reduced by integrating the ECU for the whole Mild Hybrid System control. Also, the reduction in both size and power loss is achieved by employing the newly developed MOS-FET module for power modulation. The efficiency of DC/DC converter is enhanced by using synchronous rectification method. The size is reduced by using a high speed switching device. Toyota Mild Hybrid System is world's first 42V PowerNet system with a 36V battery and has attained higher fuel economy by 15 % in the 10 - 15 (driving) mode. This is owing to the structure consisting of the above mentioned various units. Since the system can be easily installed on other power trains, it is highly practical. It is expected that the system will contribute to facilitate more extensive use of low pollution cars in years to come.
