The aim: Create a 3.3V source from a –5V supply. You can obtain a precise, positive-output voltage from a negative-voltage supply with a boost converter and a linear regulator. The input and output ...

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 ...

The circuit shown in Figure 1 illustrates one of the most basic versions of the buck-boost voltage regulator. An electrical switch is connected in series with the line input to regulate the circuit.

Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained.

Portable battery-operated electronic equipment is becoming packed with more features requiring larger amounts of power, leading to decreased operating times between battery charges. Innovations such ...
