The Story of Sakichi Toyoda
Sakichi Toyoda, the founder of Toyota Industries Corporation, possessed a strong ambition to contribute to society from his days as a youth. He had devoted his 63-year-long life to invention.
The DC-DC converter for the Prius converts the 201V high voltage from the battery to the 12V required for the auxiliary equipment. The development of a new, high heat-dissipation thick copper substrate has resulted in a smaller, more lightweight DC-DC converter. Toyota Industries’ DC-DC converters have been installed in successive generations of the TOYOTA Prius.
The DC-DC Converter for the Lexus RX450h converts the 288V high voltage from the battery to the 42V required for the electrical power steering. Through effective placement of the filter, radio noise has been suppressed and high efficiency has been achieved.
When the engine restarts, the voltage supplied from the auxiliary battery momentarily drops. The DC-DC converter for start/stop system supplies stable voltage in order to protect on-board equipment such as the audio system, navigation system, and meters against this voltage drop.
