To meet the market demand, Panasonic has succeeded in commercializing a power choke coil suitable for in-vehicle power supply circuits, with one of the lowest DC resistances in the industry*1.
The power source is characterised by the illumination of the technical contradiction between the requirement on the high quality of output electrical energy and the amount of stored energy, built up in the output circuits, as a result of producing the high-frequency transducer section of the device in the form of a multiphase circuit in which the inverter part has the form of a group of half-breach inverters with current-restricting choke coils at the output.
The common-mode choke coil must have two key features to make it an effective solution: a high common-mode impedance and a high magnetic coupling factor.
Mass production of the CM01H900 choke coil began in April 2008, with monthly production expected to reach 15 million units by the end of 2008.
This has resulted in higher demand for choke coils (the main component in DC-DC converters) with higher current capacity, lower DC resistance (RDC) and smaller physical size.
