Boost power supplies are popular for creating higher dc voltages from low-voltage inputs. As the power demands from these supplies increase, however, a single power stage may be insufficient. This ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

Traditional power-supply design practices place much emphasis on the selection and placement of the output capacitor to meet tight ripple and noise requirements. Customers are willing to spend money ...

Both zeta and Sepic have the same transfer function: Vout=Vin x D/(1-D). BTW, this is also the boost converter equation, and Cuk follows the same equation except that the output is inverted. To my ...

Many portable devices use LCD displays. These displays need large positive and negative power supplies, but most mobile devices have power rails at 5 V, 3.3 V or even lower. Thus, the challenge is not ...
