New Power Architecture for AC/DC Converters
The company claims that the new architecture is an alternative to active clamp flyback (ACF) and quasi-resonant (QR) topologies. However, it does operate in a similar way to the ACF topology. According to Eggtronic CEO, Igor Spinella the secret sauce is in the custom controller, which runs an algorithm to ensure that Ze

AC or DC? Powering Intelligent Buildings

Click image to enlarge

Figure 1: The DC-powered home

Most electronics requires DC at board level and even motor-driven AC machines are often ‘smart’, inverter-driven types, that operate internally from a high voltage DC bus. At the same time, buildings are becoming more ‘intelligent’ adding convenience, productivity and reducing energy consumption. This ca

Transportation and Electrification
It has been a challenging and often frustrating year for us all and hopefully next year will give us a fresh start, or at least put us on the path to one. The chip shortage has persisted longer than most analysts thought and it may now be the middle of next year before the fabs have caught up with demand. The sh

Figure 1: The system block diagram (left) showing three main components: the two converter modules, each with a gate driver, and the controller. The power modules mounted on the cold plate (A), and then in the power core with gate drivers (B), are also shown outside the dual inverter enclosure (C). Handles and feet are provided for portability, (D) shows the 204 mm x 267.5 mm cross section

The traction drive is where nearly all of an electric vehicle’s (EV’s) energy is put to use. The drive system must, therefore, perform with the highest possible efficiency while occupying the smallest possible space with the lowest weight — all to maximize the EV range. With the use of dual drives to enhance tr
