In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

Through a YouTube video, Professor Raja Ayyanar of Arizona State University bought to my attention an all-positive version of the Cuk (‘chook’) converter, which ...

The drive to increase efficiency and reduce the size of switching power supplies has proliferated into just about every aspect of industrial, consumer, and lighting electronics. The simple step-down ...

Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

As electronics become more advanced, the need for efficient power management increases. One crucial element of power management is the DC-DC converter, which is a device that converts DC voltage from ...

Power supplies for today's high-performance microprocessors require high-current, low-voltage dc-dc converters with fast transient responses. Such supplies must deliver currents of greater than 100 A ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...
