The heating, ventilating, and air conditioning (HVAC) market is growing at a 6% compound annual growth rate as annual shipments of AC systems are expected to grow from 110 million units in 2020 to 140 million units in 2024.¹ Large commercial systems will have the highest growth rate resulting from the construction of new healthcare, education, warehouse, government office, and retail facilities.

Designed for industrial applications, including factory automation, Energy Storage Systems (ESS),  and electric vehicle (EV) wall chargers

Littelfuse announced the new EV1K Series Fuses, the first Automotive Grade fuse with a rating of 1000 Vdc. The fuses are designed and tested to meet the overcurrent circuit protection needs of the eMoblilty market, specifically electric vehicle (EV) applications.

Provides exceptional protection for electronics used in appliances, building automation, outdoor lighting, and smart meter applications

Previous articles have discussed several high data rate interfaces such as power-over-ethernet (PoE), USB, HDMI, DisplayPort, and eSATA. This article addresses protection schemes for low-speed interfaces. The discussion will also extend to the power line frequencies and present several protection methods for the AC and DC power supplies.

Accurate and reliable data transmission is the goal for all communication circuit designs. Electronics designers can choose from several communication protocols to address their application’s needs. To ensure minimal signal interference, maximize signal/noise, and optimize error correction algorithms, designers need to protect the input and output ports from damage.

Designers often neglect to consider that electrostatic discharge (ESD) and power-line induced transients can impact the electronic circuitry not directly connected to the AC power line. If they are designing devices with communication links, they need to ensure the data port circuitry is operating reliably at all times.
