A Push-Pull Topology for DC-DC Converter 12 V EV Applications

Click image to enlarge

Figure 1. A push-pull converter helps to streamline an isolated power supply design in 12V EV applications.

DC-DC converters are employed in many high voltage applications such as ultra-capacitor energy banks, motor drives, high voltage battery systems and solar inverters. They’re one of the fundamental blocks of a power electronic design and are used to ‘condition’ voltage from one level to another – either to

Figure 1: Input current and ripple with in phase switching (red) and out-of-phase switching (blue)

There are trade-offs to make when choosing between a single output regulator and a dual output regulator. In this article, I will discuss the advantages of both and highlight when to use one or the other, using the single 6-A TPS543620 output DC/DC regulator and dual 6-A TPS541620 output DC/DC regulator from Texa

CES Loses Sense of Majesty on the Virtual Stage
This year, CES traded the glitz and glamour of Vegas for the sobering reality of COVID-19. The Consumer Technology Association, which owns and produces the show, breathlessly declared “CES 2021 Makes History as Largest Digital Tech Industry Event,” but it was less a grand proclamation than a whimper. If you’re

End of the Winter Blues
Welcome to the February issue of PSD. It has felt a longer than normal winter here in Scotland under lockdown, but both the winter and the lockdown seem to be coming to an end, albeit it little bit more slowly for the latter. With vaccines starting to become widely available, hopefully we can get back into our of

Selecting Power Inductors

Table 1

When the power supply voltage is decreased, voltage fluctuations can become more dangerous, requiring a high-performance DC-DC converter in order to operate within safe parameters. DC-DC converters can help to address these requirements, and power inductors are crucial components that affect DC-DC converters’ pe
