Microchip Makes it Simpler to Design an On-Board Charger Resolution

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

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 crucial software 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) immediately pronounces 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 package deal.

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 strengthened isolation with sturdy noise immunity and the mSiC MOSFETs’ lowered switching losses and improved thermal administration capabilities. To additional simplify the provision 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 growth and testing, Microchip affords 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 group with devoted assets 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,” stated Joe Thomsen, company vp of Microchip’s digital sign controller enterprise unit. “As a number one provider to OEMs and Tier-1s, Microchip affords 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 elements on this OBC resolution:

• The dsPIC33C DSC is AEC-Q100 certified and includes 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 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 package deal supporting strengthened isolation and SOIC-8 narrow-body supporting fundamental isolation. Appropriate with the dsPIC33 DSC, the MCP14C1 is optimized to drive mSiC MOSFETs by way of Undervoltage 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 sturdy noise immunity and excessive Widespread-Mode Transient Immunity (CMTI).
• The mSiC MOSFET in an AEC-Q101-qualified D2PAK-7L XL floor mount package deal contains 5 parallel supply sense results in cut back switching losses, improve present functionality and reduce inductance. This system helps 400V and 800V battery voltages.

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