Switched Capacitor DC-DC Converters
The last century since the late 70s, with the design and manufacture of integrated circuit technology, a variety of electrical equipment to gradually develop in the direction of small-scale, corresponding to study compatible with the small size, light weight, high efficiency power supply has become an important topic of interest. Switching power supply using the traditional soft-switching technology, by increasing the switching frequency can reduce the volume of power, but because the structure contains inductors and transformers, and thus restricting the power to further reduce the size. Sheet inductance is now available although there is still not satisfactory.In recent years, a new type of switched-capacitor converters, this converter does not contain the structure of inductors and transformers, only by the capacitor network and constitute a switch, it is expected to further reduce the power of the volume, even in the chip to achieve integration, based on these significant advantages, this converter increasing the widespread interest aroused.
