Microchip Makes it Easier to Design an On-Board Charger Solution

CHANDLER, Ariz., June 10, 2024 (GLOBE NEWSWIRE) — The market for Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs) continues to grow as the push towards decarbonization requires sustainable solutions to reduce emissions. A critical application for EVs is the on-board charger, which converts AC power into DC power to recharge the vehicle’s high-voltage battery. Microchip Technology (Nasdaq: MCHP) today announces an On-Board Charger (OBC) solution that uses a selection of its automotive-qualified digital, analog, connectivity and power devices, including the dsPIC33C Digital Signal Controller (DSC), the MCP14C1 isolated SiC gate driver and mSiC™ MOSFETs in an industry-standard D2PAK-7L XL package.

This solution is designed to increase an OBC system’s efficiency and reliability by leveraging the dsPIC33 DSC’s advanced control functions, the MCP14C1 gate driver’s high-voltage reinforced isolation with robust noise immunity and the mSiC MOSFETs’ reduced switching losses and improved thermal management capabilities. To further simplify the supply chain for customers, Microchip provides the key technologies that support the other functions of an OBC, including communication interfaces, security, sensors, memory and timing.

To accelerate system development and testing, Microchip offers a flexible programmable solution with ready-to-use software modules for Power Factor Correction (PFC), DC-DC conversion, communication and diagnostic algorithms. The software modules in the dsPIC33 DSC are designed to optimize performance, efficiency and reliability, while offering flexibility for customization and adaptation to specific OEM requirements.

“Microchip established an E-Mobility megatrend team with dedicated resources to support this growing market, so in addition to providing the control, gate drive and power stage for an OBC, we can also provide customers with connectivity, timing, sensors, memory and security solutions,” said Joe Thomsen, corporate vice president of Microchip’s digital signal controller business unit. “As a leading supplier to OEMs and Tier-1s, Microchip offers comprehensive solutions to streamline the development process, including automotive-qualified products, reference designs, software and global technical support.”

Here is an overview of the key components in this OBC solution:

Microchip has published a white paper that provides more information about how this OBC solution can optimize a design’s performance and speed up its time to market.
