Condensatori: nuove tecnologie e nuovi prodotti in circuiti di potenza con Wide Bandgap Semiconductor

Attilio Zucaro FAE di Yageo Kemet East Europe – by Rutronik 

Con l’avvento della tecnologia dei WBG, le performance richieste ai condensatori di potenza stanno aumentando. L’incremento delle frequenze di switching, le temperatura più elevate e la spinta verso la miniaturizzazione rappresentano una sfida per i produttori di condensatori in applicazioni di potenza.

Reduce Motor EMI and Insulation Voltage Stress with Slew Rate Control Gate Driver

Saeed Safari, Field Application Engineer Industrial Products Broadcom   

In motor drives, easy control and high efficiency are some of the many benefits of variable speed or frequency drives (VSD/VFD). However, the operation of these pulse-width modulation (PWM) driven motors causes a few negative effects in the equipment, such as: damage to the motor’s insulation and bearings due to the excessive dv/dt voltage. Signal errors in equipment can arise due to strong EMI generated by PWM driven motors. These negative effects degrade the lifetime and performance of the motor.

Existing solutions use expensive and bulky dv/dt filters which lead to efficiency losses. In this presentation, we will introduce the new slew rate control smart gate drive technology, to control the dv/dt of the IGBT dynamically. This new method has 2 levels of slew rate control which change the strength of its output current, driving the gate of the IGBT. Depending on the motor current loading condition, the dv/dt and switching loss will be optimized by this method, as it controls its output driving strength dynamically. This simple and cost-effective method of controlling the IGBT slew rate will help to improve the lifetime and performance of the motor.

Key takeaways from this presentation are:

• Understand how the PWM technique and the long cable between drive and motor cause excessive dv/dt voltage
• Recognize the many negative effects to the motor due to the high dv/dt
• Discover how the new slew rate control smart gate drive solves dv/dt issues
• Learn about other smart gate drive features that can protect the IGBT and improve the lifetime of the inverter

Future-proofing EV Chargers

Steve Roberts, Innovation Manager at Recom

The topic is how to design existing and planned EVSE (Electric Vehicle Supply Equipment) so that different types of power transistors such as IGBT, Silicon, SiC, Cascode and GaN can be easily be used, even if their gate drive voltages are not the same. This is a particular problem with SiC as each new generation has different recommended and maximum gate drive voltage limits.

Leakage Diagnostics in Battery Thermal Management Systems

Andreas Mangler, Director Strategic Marketing – Member of the Extended Management Board di Rutronik Electronics Worldwide

Machine Learning Electronic Nose detects various gases and cooling liquid ejection products

Avoiding Thermal Runaway (TR) is one of the key criteria for Battery Thermal Management Systems (BTMS). The root cause of TR may be induced by mechanical, electrical and/or thermal abuse. It should be also noted that during thermal runaway venting occurs. During the process of venting, various materials are rejected from the cells, including gases, liquids and solids. Gaseous ejection products mainly contain carbon dioxide, carbon monoxide, hydrogen and short-chain hydrocarbons, such as methane and ethylene, most of which are flammable. Various single-phase coolant fluids have received immense interest in the area of BTMS. So, leakage diagnostics of battery cooling systems are also very important functions. Based on a machine learning edge intelligence embedded MCU and several environmental sensors, an electronic nose will be presented suitable for mass production in BTMS.

Lo sviluppo delle CER è basato sulla massiccia integrazione dei veicoli elettrici nella rete intelligente. Per questo scopo è necessario sviluppare sistemi di misura e controllo avanzati (AMI – Advanced Metering Infrastructures) e algoritmi di controllo dei sistemi di ricarica basati su tecniche di intelligenza artificiale in grado di sfruttare anche le opportunità offerte dalla blockchain e dalla rete 5G.

HESS – Hybrid Energy Storage System based on lithium-Ion Battery and Super Capacitors

Andreas Mangler, Director Strategic Marketing – Member of the Extended Management Board di Rutronik Electronics Worldwide

3-Phase Bidirectional DC/DC Converter for 48V Power Net

Together with the University of Applied Science Zwickau and a leading engineering service provider, Rutronik has developed a completely new hybrid energy storage system (HESS). Combining battery and Super Cap, it improves the peak current characteristics of the energy storage system, significantly extends battery life and can be adapted as required thanks to digital control. In this way, it ensures maximum reliability in a wide range of applications with little design effort.

This technology is based on a RUTRONIK own patented solution, which offers a predictive load current slew rate di/dt measurement within a few nanoseconds, in order to bypass the digital control loop to offer lowest latency and fastest switching.

With this project, Rutronik has demonstrated that any battery system can be combined with Super Caps in practice. This is because this combination allows an ideal division of labor: while the battery constantly supplies energy for continuous power, the Super Cap takes over the short-term peak currents and voltages. The discharge current of the battery is limited to its nominal current so that it never leaves its optimum operating range. This “gentle operation” extends its lifetime (RuL) by up to 100 percent. In addition, the inner temperature of the battery is significantly lower and in the ideal operation temperature range, thus preventing premature degradation and improve the lifetime.
