HEV/EV on-board charger (OBC) & wireless charger

Advances in real-time control have increased processing capabilities and expanded sensing and actuation performance, resulting in higher precision and efficiency to make vehicles more affordable.

Benefits include: 

• Reduced size and weight: low latency control loops and high resolution PWMs enable higher switching frequencies which reduce the physical size and weight of passives and magnetics.
• Improved power density and efficiency: unlock the benefits of wide band-gap (WBG) gallium nitride and silicon carbide semiconductors that require 100-kHz to 1-MHz switching frequencies.
• System integration to reduce cost: cores and peripherals enable advanced power topologies and support the integration of multiple power conversions on a single MCU.

A gate driver provides galvanic isolation between the input and output and drives the insulated-gate bipolar transistor-, silicon- or silicon carbide-based power factor correction stage.

Benefits include:

• Improved system-level efficiency: minimized switching and conduction losses that include turnon and turnoff energy.
• Reduced overall system size and weight: increased switching frequencies enable a significant reduction in overall system magnetics and weight, while a dual-channel driver implementation reduces overall printed circuit board area and bill of materials compared to single-channel options.
• System reliability: galvanic isolation and high common-mode transient immunity increase system resilience to transients and noise.

Optimize costs while improving power density and efficiency to meet your system requirements. Choose from a portfolio of bias power supplies with integrated field-effect transistors (FETs) and magnetics, integrated FETs and external magnetics, or external FETs and external magnetics.

Benefits include:

• Improved power density and efficiency in a small footprint, with >150-V/ns common-mode transient immunity and mitigated electromagnetic interference.
• Streamlined functional safety, with International Organization for Standardization 26262 compliance and system-level diagnostics and protection.
• Protected power modules, with high load regulation accuracy and thermal performance.

Achieve accurate, low-latency current and voltage measurements with high common-mode transient immunity and working voltages, thereby improving the system efficiency, reliability and performance of onboard charging systems.

Benefits include:

• Capacitive isolation, which enhances safety and lowers system costs.
• High bandwidth for faster control and reaction times, enabling higher system reliability and better performance.
• Easier design complexity, which eliminates the need for external protection.
