| Abstract;A smaller and more powerful 12V DC-DC converter has been developed for Honda's Integrated Motor Assist (IMA) system. Low breakdown voltage FETs and a beam lead diode module in combination with high-efficiency soft switching circuits have reduced energy loss to increase the efficiency of the unit. Heat dissipation simulations were employed to optimize the component layout for efficient cooling. The new unit employs a digital signal processor, and the reduction in component numbers enabled by digital control has resulted in a 40% reduction in the size of the circuit board of the control section. The application of these technologies has enabled the unit volume to be decreased by 17% while output current has been increased by 60% against the former model. (author abst.) |
