Higher efficiency for EV DC charging and other industrial applications
It has been announced that Infineon Technologies is extending the CoolSiC Schottky 1,200V G5 diode portfolio with the release of a TO247-2 package. It can easily replace silicon diodes for higher efficiency. The expanded 8.7mm creepage and clearance distances offer extra safety in high-pollution environments.
SiC inverter evaluation system for increased EV efficiency
The Silicon Valley start-up that is delivering soft switching for DC/AC and AC/DC power conversion, Pre-Switch, has announced its CleanWave 200kW silicon carbide (SiC) automotive inverter evaluation system that enables power design engineers to investigate the accuracy of the company’s soft switching architecture and platform over varying load, temperature, device tolerance and degradation conditions.
High temperature gate drivers at PCIM 2019
Specialist in high temperature semiconductors, CISSOID, will present new High Temperature Gate Drivers, SiC MOSFET’s and IGBT Power Modules at PCIM 2019, the exhibition and conference for power electronics, intelligent motion, renewable energy, and energy management.
Micro IPM adds IGBT based IM231 series for highest power density
Infineon Technologies is introducing its CIPOS Micro IM231 series, a family of 600V rated Intelligent Power Modules (IPM). It is qualified for harsh humid environments, passing 1,000 hours of high voltage, high temperature and high humidity reverse bias (HV H3TRB) stress testing. For this reason, the energy-efficient IPM suits power appliance motor drives particularly in circulator hydronic pumps, drain pumps for washing machines, dishwashers, an...
FPGAs use AI for soft switching
AI can be used to implement soft switching and minimise power conversion switching losses, argue Derek Kroes and Bruce Renouard, Pre-Switch
MOSFETs enables energy savings for inverters in AC systems
A new lineup of its PrestoMOSTM series of 600V super junction MOSFETs that includes 30 new models, has been announced by ROHM. This series increases design flexibility while maintaining the industry’s fastest reverse recovery time (trr) optimised for EV charging stations and motor drive in home appliances such as refrigerators and Air Conditioners (ACs).
High insulation optocouplers minimise creepage
Claimed to be the industry’s highest insulation voltage optocouplers, the 5A gate drive ACNT-H343 optocoupler is from Broadcom.
Broad 12mm power module portfolio without base plate
It has been announced that Infineon Technologies has extended its Easy family to include a new package: Easy 3B. Together with the other Easy 1B and 2B packages, this comprises the broadest power module portfolio at 12mm height without base plate. Easy 3B is a well suited platform to extend current inverter designs to achieve higher power without changing much on the mechanical side.
Broad portfolio of CoolSic MOSFETs in discrete housing launched
Infineon Technologies enters high volume production of a comprehensive portfolio of 1,200V CoolSiC MOSFET devices. They are rated from 30-350mΩ and implemented into TO247-3 and TO247-4 housings. The expansion includes a surface mount device (SMD) portfolio and a 650V CoolSiC MOSFET product family, both to be launched soon.
High insulation voltage optocouplers with 15mm creepage
A new five amp gate drive optocoupler, the ACNT-H343, has been introduced by Broadcom. This new member of the ACNT optocoupler family features more than 100kV/us of high noise immunity and three times faster propagation delay than the previous generation.
