Electrical Vehicle AC Chargers

Littelfuse provides a wide range of products that are suitable for Electric Vehicle AC Chargers. Although simpler in nature compared to DC chargers, AC charging stations safely deliver AC power from the electrical grid into the vehicle. Due to space and weight constraints in the vehicle, on-board chargers and AC charging stations are typically limited to lower amounts of power (22kW or less), which means charging time is slow – taking several hours. These systems also rely on a vehicle’s on-board charger to enable the conversion of AC power from the grid into DC power to charge the vehicle’s battery. It’s critical that proper measures are taken to safeguard both the charger and vehicle.

AC/DC Power Supply

Littelfuse AC/DC Power Supply is a commonly used building block in electronic designs. The components in these power supply building blocks need to be reliable and long-lasting, and Littelfuse offers a range of products that fit those requirements. This portfolio of components covers overcurrent and overvoltage protection, the power stage, and output protection. Typical applications for Littelfuse AC/DC Power Supply products include automotive, solar, industrial, manufacturing, and more.

Transient Voltage Suppressor (TVS) Diodes

Littelfuse TVS (Transient Voltage Suppression) Diodes are a broad range of circuit protection products designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). Lightning strikes, inductive load switching, and ESD cause electrical over-stresses associated with the transmission on data lines and electronic circuits. Offered in a variety of surface mount and through-hole circuit board mounting formats, the TVS Diode portfolio includes high peak pulse current and peak pulse power options up to 20kA and 30kW, respectively. Littelfuse TVS Diodes are chosen for the fast response time (low clamping voltage), lower capacitance, and low leakage current. TVS Diodes are available in both unidirectional (unipolar) or bidirectional (bipolar) diodes circuit configurations. 

Heat Pumps

Littelfuse provides a broad portfolio of components for heat pumps, including fuses, TVS diodes, gate drivers, and more. The heat pump market is growing quickly, driven by government initiatives to reduce greenhouse gas emissions and rising energy costs. With inverter-driven motors improving system efficiencies, heat pumps can now be used in a wide range of climates. Learn how Littelfuse technologies make heat pumps safer, more reliable, and more energy efficient. Heat pumps can be used in a wide range of climates due to the inverter-driven motors improving system efficiencies.
