Microchip Makes It Simpler To Design An On-Board Charger Resolution

The marketplace for Battery Electrical Autos (BEVs) and Plug-in Hybrid Electrical Autos (PHEVs)
continues to develop because the push in the direction of decarbonization requires sustainable options to cut back emissions. A essential utility for EVs is the on-board charger, which converts AC energy into DC energy to recharge the car’s high-voltage battery. Microchip Expertise (Nasdaq: MCHP) at this time publicizes an On-Board Charger (OBC) answer that makes use of a choice 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 answer 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 strengthened isolation with strong noise immunity and the mSiC MOSFETs’ lowered switching losses and improved thermal administration capabilities. To additional simplify the availability chain for patrons, Microchip supplies the important thing applied sciences that help the opposite features of an OBC, together with communication interfaces, safety, sensors, reminiscence and timing.

To speed up system improvement and testing, Microchip provides a versatile programmable answer 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 workforce with devoted sources to help this rising market, so along with offering the management, gate drive and energy stage for an OBC, we are able to additionally present clients with connectivity, timing, sensors, reminiscence and safety options,” stated Joe Thomsen, company vice chairman of Microchip’s digital sign controller enterprise unit. “As a number one provider to OEMs and Tier-1s, Microchip provides complete options to streamline the event course of, together with automotive-qualified merchandise, reference designs, software program and world technical help.”

Right here is an summary of the important thing parts on this OBC answer:

• 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 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 strengthened isolation and SOIC-8 narrow-body supporting primary isolation. Appropriate with the dsPIC33 DSC, the MCP14C1 is optimized to drive mSiC MOSFETs viaUndervoltage Lockout (UVLO) for V GS = 18V gate drive break up output terminals, which simplifies implementation and eliminates the necessity for an exterior diode. Galvanic isolation is achieved by leveraging capacitive isolation know-how, which leads to strong noise immunity and excessive Widespread-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 scale back switching losses, enhance present functionality and reduce inductance. This system helps 400V and 800V battery voltages.
