Designers can velocity time to marketplace for their on-board charger utility with key applied sciences from one provider, together with the management, gate drive and energy stage

CHANDLER, Arizona — The marketplace for Battery Electrical Automobiles (BEVs) and Plug-in Hybrid Electrical Automobiles (PHEVs) continues to develop because the push in direction of decarbonization requires sustainable options to cut back emissions. A vital utility for EVs is the on-board charger, which converts AC energy into DC energy to recharge the automobile’s high-voltage battery. Microchip Expertise (Nasdaq: MCHP) yesterday introduced an On-Board Charger (OBC) solution that makes use of a number of its automotive-qualified digital, analog, connectivity and energy gadgets, together with the dsPIC33C Digital Sign Controller (DSC), the MCP14C1 remoted SiC gate driver and mSiC™ MOSFETs in an industry-standard D2PAK-7L XL bundle.

This resolution is designed to extend an OBC system’s effectivity and reliability by leveraging the dsPIC33 DSC’s superior management features, the MCP14C1 gate driver’s high-voltage bolstered isolation with strong noise immunity and the mSiC MOSFETs’ decreased switching losses and improved thermal administration capabilities. To additional simplify the provision chain for purchasers, Microchip gives the important thing applied sciences that assist the opposite features of an OBC, together with communication interfaces, safety, sensors, reminiscence and timing.

To speed up system improvement and testing, Microchip gives a versatile programmable resolution with ready-to-use software program modules for Energy Issue Correction (PFC), DC-DC conversion, communication and diagnostic algorithms. The software program modules within the dsPIC33 DSC are designed to optimize efficiency, effectivity and reliability, whereas providing flexibility for personalisation and adaptation to particular OEM necessities.

“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,” mentioned Joe Thomsen, company vp of Microchip’s digital sign controller enterprise 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.”

Right here is an outline of the important thing elements on this OBC resolution:

• The dsPIC33C DSC is AEC-Q100 certified and incorporates a high-performance DSP core, high-resolution Pulse-Width Modulation (PWM) modules and high-speed Analog-to-Digital Converters (ADCs), making it optimum for energy conversion functions. It’s useful security prepared and helps the AUTOSAR^® ecosystem.
• The MCP14C1 remoted SiC gate driver is AEC-Q100 certified and is obtainable in SOIC-8 wide-body bundle supporting bolstered isolation and SOIC-8 narrow-body supporting fundamental isolation. Suitable with the dsPIC33 DSC, the MCP14C1 is optimized to drive mSiC MOSFETs by way of Undervoltage Lockout (UVLO) for V_GS = 18V gate drive cut up output terminals, which simplifies implementation and eliminates the necessity for an exterior diode. Galvanic isolation is achieved by leveraging capacitive isolation expertise, which ends up in strong noise immunity and excessive Widespread-Mode Transient Immunity (CMTI).
• The mSiC MOSFET in an AEC-Q101-qualified D2PAK-7L XL floor mount bundle consists of 5 parallel supply sense results in scale back switching losses, improve present functionality and reduce inductance. This gadget helps 400V and 800V battery voltages.

Microchip has revealed a white paper that gives extra details about how this OBC resolution can optimize a design’s efficiency and velocity up its time to market.
