across the power switches.
Each leg of the NPC inverter
has four transistors that can

be controlled, giving 24=16
total possible states, but
only three of these states
are feasible, as others create
short-circuits on the DC-link.

FUTURE OF EV
CHARGING
The transformation from

combustion engines to EVs
is a long-term process. Many
oil companies are already
claiming a stake in the EV
networks by creating charging
stations or promoting products

Future expected works look
forward to using MLCs in FCs to benefit from the various advantages of these converters while Taking on Home
proving high-power and ultra-fast charging systems for EVs. To help EVs reach ubiquity, governments
and EV charging companies must ensure the availability of fast-charging infrastructure. Without an
efficient charging infrastructure, EV uptake may be a slow-rolling process. Energy Waste from
Vampire Devices

By Saumitra Jagdale, contributing writer for Power Electronics News

According to current research, the global cost of living shows no signs of improvement due to the
rising population. Furthermore, energy consumption is increasing as a result of unsatisfied consumer
demands. According to reports, domestic appliances waste approximately 20% of all electricity. These
energy vampires have the potential to save money and energy by reducing rising demand.

OVERVIEW OF VAMPIRE DEVICES

Any device that uses energy even after being turned off or when not in use is referred to as a
vampire device. Integrated circuits are used in devices that automate and simplify routine actions
like turning on the TV or a coffee maker. Even while in idle mode, these circuits use the internet
actively for ongoing updates and monitoring, which uses energy.
