Most engineers are familiar with boost converters, which step up the output voltage (V OUT ) to a value that exceeds the input voltage (V IN ). They are also familiar with buck-boost converters and single-ended primary-inductor converter (SEPIC), ...

Synchronous rectifiers are MOSFETs, driven in such a way as to perform a rectifying function. They often take the place of diodes in the output-rectification stage of switching power converters, because of their lower on-state power loss. In power ...

A solar-powered lead-acid battery charger can ensure that the battery remains fully charged over a wide temperature range. The ideal charging circuit compensates for temperature and sunlight variations, including recovery from shading. Solar or ...

A bi-directional current source for a grounded load will always have some complication in its construction. The improved Howland Current Pump as shown in Figure 1 is the most frequent choice for this function. The Howland requires carefully matched ...

Figure 1 shows a typical using of LM350 ( LM317 ) adjustable regulator when you need to adjust its output voltage. Figure 1. This voltage is approximately given here as: The potentiometer R2 is often the most unreliable part of the circuit. As ...

It’s the mid 1990’s and I am a design engineer for a company that designs and manufactures custom measurement systems and high power electronics. Our customers range from experimental fusion reactor operators to electric utilities. One ...

At times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an AM or FM modulation scheme. However, they tend ...

This article will describe how Bode plots can be used as a tool to quickly assess if your power supply design will meet the requirements for dynamic control behavior. Power supplies normally maintain a fixed output voltage via a control loop. This ...

In test-and-measurement applications, you must provide overvoltage protection for the output terminals of amplifiers, power supplies, and similar components. The conventional way to accomplish this task is to add series resistors with the output ...

There are thousands of different switching regulators on the market. Selection is based on specifications such as input voltage range, output voltage capability, maximum output current, and a slew of other parameters. This article explains current ...
