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 the direction of decarbonization requires sustainable options to scale back emissions. A crucial utility for EVs is the on-board charger, which converts AC energy into DC energy to recharge the car’s high-voltage battery. Microchip Know-how (Nasdaq: MCHP) yesterday introduced an On-Board Charger (OBC) resolution 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 capabilities, the MCP14C1 gate driver’s high-voltage bolstered isolation with sturdy noise immunity and the mSiC MOSFETs’ decreased switching losses and improved thermal administration capabilities. To additional simplify the provision chain for patrons, Microchip gives the important thing applied sciences that help the opposite capabilities 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 personalization and adaptation to particular OEM necessities.

“Microchip established an E-Mobility megatrend staff with devoted sources to help this rising market, so along with offering the management, gate drive and energy stage for an OBC, we will additionally present clients with connectivity, timing, sensors, reminiscence and safety options,” mentioned Joe Thomsen, company vp of Microchip’s digital sign controller enterprise unit. “As a number one provider to OEMs and Tier-1s, Microchip gives complete options to streamline the event course of, together with automotive-qualified merchandise, reference designs, software program and international technical help.”

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

  • The dsPIC33C DSC is AEC-Q100 certified and contains 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 purposes. It’s purposeful 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 primary isolation. Appropriate with the dsPIC33 DSC, the MCP14C1 is optimized to drive mSiC MOSFETs through Undervoltage Lockout (UVLO) for VGS = 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 leads to sturdy noise immunity and excessive Frequent-Mode Transient Immunity (CMTI).
  • The mSiC MOSFET in an AEC-Q101-qualified D2PAK-7L XL floor mount bundle contains 5 parallel supply sense results in cut back switching losses, enhance present functionality and reduce inductance. This machine 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.
