Addressing the growing market for automotive traction inverters
ON Semiconductor has released the first two devices from its new VE-Trac family of power modulesfor high voltage automotive traction inverters. These two Power Integrated Module (PIM) devices bring electrical and thermal performance while providing scalability and automotive reliability to the rapidly growing market for traction inverters.
Isolated gate drivers and EMI noise
In power electronics isolated gate drivers are used to drive power semiconductors like IGBTs and power MOSFETS. The gate drivers are used to provide galvanic isolation between the control circuits and the high voltages. They are also used for level shifting to provide high gate voltage and current to switch the IGBT.In industrial applications like inverters and motor drives, EMI noise will be generated by an inductive mode-like motor. The noise m...
SiC FETs with RDS(on) deliver increased efficiency
UnitedSiC, a manufacturer of silicon carbide (SiC) power semiconductors, is introducing four new SiC FETs, with RDS(ON) levels as low as 7mohms, delivering unprecedented levels of performance and efficiency for use in high-power applications such as electric vehicle (EV) inverters, high-powered DC/DC converters, high-current battery chargers and solid-state circuit breakers.
Soft-switching gate driver slashes solar inverter costs
Pre-Switch has announced that its soft-switching IGBT and silicon carbide gate driver architecture, including the Pre-Drive3 controller board, powered by the Pre-Flex FPGA, and RPG gate driver board, can reduce the cost of solar inverters. The two-stage architecture delivers the same switching loss performance as a five-level design, resulting in reduced cost, control complexity and BOM count.
Integrated device offers protection against voltage fluctuations
Toshiba Electronics has announced the launch of a new three-phase brushless motor driver for home appliances such as air-conditioners and air-purifiers. The new TB67B000AHG driver is also suited for use in a wide variety of industrial applications. This high voltage device extends and expands the existing TB67B000 series of drivers that delivers highly energy efficient motor drive and noise reduction in a single, integrated package.
Overcoming EV range anxiety wirelessly
The automotive industry is undergoing one of the biggest periods of change in its history as drivetrains migrate from the internal combustion engine (ICE) to electric motors. While technology development is making great strides in increasing the range of modern electric vehicles (EV), one of the greatest impediments to adoption is consumer concern about being stuck with a flat battery – the so-called ‘range anxiety’.
Software plug-in hastens double pulse testing
Double pulse testing in less than a minute is now possible on the Tektronix AFG31000 arbitrary/function generator with the availability of a new software plugin. It saves significant time compared to alternative methods.
High-performance MOSFET for e-bike market
MagnaChip Semiconductor has announced the release of a 100V Mid-Voltage MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) with a new thermal package (M2PAK-7P) designed for the fast-growing e-Bike market. This MOSFET with M2PAK-7P is suitable to meet the particular requirements of electric bike (e-Bike) systems.
Three-phase inverter reference design for VAC drives
This reference design from TI realises a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. The UCC23513 gate driver used has a six-pin wide body package with optical LED emulated inputs which enables its use as pin-to-pin replacement to existing opto-isolated gate drivers.
