Introduction

 It is important to get new technology in place to reduce losses in any kind of application in electronic equipment. Wide band gap devices can contribute a significant amount in new design.The two types of products cover both a specific voltage range and have a small overlap.So GaN serves up into the range of line voltages while SiC can serve kilo volts

Design Skills of Gapped Ferrite Materials for Inductor and LLC Transformer

Magnetic component is a key factor for great power converter applications where the magnetic core loss of required resonant inductors and transformers a large part of the total power loss. Thus, the accurate core loss value is a must for prospective magnetic design. less attention is focused on the thermal dissipation effect and its impact on the material thermal performance. Besides, the uncertainty always occurs for core loss estimation on gapped cores for inductor and transformer design, LLC design is studied and analysed.

Control Architecture Unleashes the Full Potential of Silicon Carbide

Hard-Switching is commonly-used in DC/AC power converters but it introduces switching losses which are responsible for a large percentage of power converter losses. Soft-switching minimizes switching losses but is has never been successfully-implemented for DC/AC systems with varying duty cycle, input voltage, temperature and load conditions. Pre-Switch employs Artificial Intelligence to successfully implement soft switching for the first time, minimizing switching losses and enabling users to benefit from the full potential of their transistors, independent of the FET technology.

Isolated Smart Gate Driver for SiC MOSFET Control

ADuM4177 is a new single channel gate driver specifically optimized for driving SiC MOSFET, realized in iCoupler® technology providing isolation between the input signal and the output gate drive.

The ADuM4177 provides isolated fault reporting for overcurrent events, remote temperature overheating events, undervoltage lockouts (UVLO) and overvoltage protections (OVP) for dual rail supply, gate error and thermal shutdown (TSD). Furthermore, high speed SPI can be used to read-out the driver’s status as well as to program numerous parameters. The ADuM4177 provides a Miller clamp control signal for external MOSFET to provide robust SiC turn off with a dual or with single rail supply. This circuit allows fast desaturation protection. Active Short Circuit (ASC) input on the secondary side allows the driver to be switched on from the secondary side. ADuM4177 has integrated low Rdson, 0.4ohm (typ) MOSFETs to drive up to 10A of peak current as well as one 0.6ohm MOSFET to realize soft shutdown.

Analysis of PCB Parasitic Effects in a Vienna Rectifier for an EV Battery Charge

This work investigates the impact of the PCB parasitics on the performances of a SiC three-level t-type rectifier used for electric vehicle battery chargers.  The high switching frequency and the fast raising edge of the rectifier enables a very efficient design. On the other hand, as the time derivative of the current increases (as a rule of thumb we can set 1A/ns as a breaking point), PCB parasitics start to play a significant role and, if not properly taken into account, may cause the degradation of the performances or even a design failure.  Industry standard EDA (Electronic Design Automation) tools can be used to extract a model for the PCB so that all the effects introduced by the physical realization of the board layout can be included in the analysis.  For the current work the software Advanced Design System by Keysight Technologies was used to extract an S-parameter based model of the PCB and co-simulate it with the circuit components.  Results obtained with and without the PCB model are compared for two different design iterations.

Optimized for Performance and Price, Let’s Go GaNFast™

For GaN – or any other new technology – performance and price determine the rate of market adoption over old, traditional Si solutions. After exceeding fundamental device-performance criteria (quality/reliability, delivery/leadtime, designer knowledge/training) then system-performance metrics (efficiency, size, form-factor, standby power) are evaluated vs. system price.

GaNFast™ power ICs deliver high-frequency, high-efficiency switching in a reliable, easy-to-use “digital-in, power-out”, monolithically-integrated format. This presentation demonstrates fundamental and system performance plus system cost examples across a range of end-customer, mass-production applications.

Reliable use of GaN Devices for a Broad Range of Applications

Gallium Nitride based power conversion systems are entering the market at an accelerating rate. Initially appearing in AC:DC systems in telecom nodes and datacenters, 600V Rated GaN HEMTs are now being designed into a wider range of applications from class D audio systems to compact adapters to television sets. As has been broadly documented, some GaN failure mechanisms are different from those that occur in silicon based power transistors. How then can designers be certain that GaN devices will perform reliably in the wider range of applications into which they are now being designed?  This talk will describe the  approach to this problem taken by Infineon.

GaN takes its place as the technology of choice for high volume power ICs

The superior efficiency of GaN transistors has made the technology interesting for power IC makers. However, until very recently, volume implementations of the technology have been few and far between. This year Power Integrations revealed that higher power members of its InnoSwitch family of flyback converter ICs and  its LYTSwitch LED driver IC family are based on the company’s own GaN technology – and have already been adopted by high volume USB-PD adapter makers for laptops and cellphones.

Though in its early stage of maturity, high-voltage GaN technology is already making great strides in the power conversion market. For example, it is currently demonstrating FIT rates similar to SiC and is in production with high volume scalability available. In this discussion, Philip Zuk from Transphorm—the manufacturer of the first qualified 650 V and 900 V GaN FETs—will explore GaN’s reliability, usability, accessibility, and practicality through the lens of the company’s successes to date. Additionally, Mr. Zuk will shed light on the adoption status of commonly targeted markets while also introducing new, viable markets made possible by the technology’s performance, reliability and manufacturability.

GaN-On-Silicon: From Switches to Intelligent Power Solutions to Boost Performance

GaN-on-Silicon power devices are recognized as a key technology to sustain future power converter systems roadmaps in the field of IT electronics, renewable solar and emission free automotive applications. Exagan implemented proprietary 200-mm’s GaN-on-Silicon technologies into high volume production to enable higher integration and improved efficiency.

Users experiences on current silicon solutions set expectations on any new product using new technology introduction. Similar “easy to use”, “predictive FIT in use” and “cost in use” are a given that needs to be part of the key attributes of the new product to meet those expectations.

G-FET™ & G-Drive™ Exagan product portfolio provides GaN-on-Silicon solutions that combine the super-fast GaN_on-Silicon switch with its appropriate driver IC controlled by embedded diagnostics, protections and, much more functionalities to become the expected modern elementary switching cell for the next century. 

Meeting user’s expectation, required reliability and cost targets, G-FET™ & G-Drive™ solutions help innovators to be able to create smaller, more efficient and higher-performing power converter applications than were possible with traditional silicon-based technology.

This paper will present the latest developments achieved and new products to be released using cost effective G-Stack™ 200-mm’s GaN-on-Silicon.
