Puls has announced three 240 or 480W DIN rail ac-dc dc-dc power supplies with an integrated EtherCAT interface for configuration, operation monitoring and remote control. Data over the bus includes voltage and current characteristics on the input and output sides, and direct connection to an EtherCAT controller is possible without intervening gateways. “Real-time data transmission makes possible the monitoring, logging ...

Omron has launched a high-capacity PCB-mount relay for switching dc in 15 to 40kW household electricity storage systems, bi-directional EV chargers and uninterruptible power systems. G9KB-E is based on the earlier G9KB family, and is the same size and weight (37 x 50mm footprint and 50mm tall), but can switch higher power, up to maximums of 800Vdc or 100A. Envisaged ...

EPC Space has created two surface-mount 40V radiation-specified GaN hemts for space use. EPC7001BSH is a 50A (120A pulse) 11mΩ transistor in 5.7 x 3.9mm packaging EPC7002ASH is a 15A (40A pulse) 28mΩ transistor in 3.4 x 3.4mm packaging “Both devices have a total dose radiation rating greater than 1,000kRad(Si) and SEE immunity for LET of 83.7MeV/mg/cm2 with Vds up ...

In the context of the explosive growth of the energy storage market. New energy storage market prospects With the increasing penetration of renewable energy, especially due to the instability of wind and solar power, the role of energy storage systems in balancing grid supply and demand and mitigating fluctuations is becoming increasingly evident. Additionally, the development of the electric vehicle ...

The test rig for OpenHydro’s first tidal turbine is being decommissioned from the European Marine Energy Centre’s Fall of Warness off the island of Eday in the Orkneys. OpenHydro, now gone as a tidal turbine company, built the rig in 2006 for its proof-of-concept 250kW turbine, and it has stood in the water ever since. It has two steel columns ...

Shanghai-based WeEn Semiconductors unveiled 650V and 1,200V IGBTs with fast recovery anti-parallel diodes at PCIM in Nuremberg. “Based on fine trench gate field-stop technology, the IGBTs provide a more uniform electric field within the chip, support higher breakdown voltages and offer improved dynamic control,” according to the company. “A positive temperature coefficient simplifies parallel operation.” Ratings are 650V 75A, 1.2kV ...

Qorvo has picked depletion-mode (normally-on) silicon carbide JFET technology to build a 750V 4.3mΩ transistor for circuit breakers, and put it in a 10 x 12mm surface-mount TOLL package. “It was designed for circuit protection applications including solid-state circuit breakers, where low resistance, thermal performance and reliability are paramount,” according to the company. This “JFET can withstand high instantaneous junction ...

Applied EV has picked Cissoid to supply silicon carbide based inverter modules for its autonomous electric vehicles. The module, CXT-ICM3SA, was introduced at APEC earlier this year and combines a three-phase 1.2kV SiC mosfet bridge – rated at 340 to 550A depending on model – a driver board and a control board in a stack. The control board is built ...

Microchip has turned to silicon carbide to create a bi-directional electric vehicle on-board charger design for 400V or 800V batteries. There are two halves: a 7.6kW bi-directional two-phase interleaved totem-pole power factor corrector, and an 11kW dual full bridge transformer-coupled bi-directional dc-dc converter. “These two designs work together,” Microchip told Electronics Weekly. “At PCIM we showed both operating in bi-directional ...

Infineon has announced a flurry of new power products as a prelude to PCIM in Nuremberg next week, the latest of which is a family of 600V super-junction mosfets. Its eighth generation, “the devices combine the best features of the 600V CoolMOS 7 series and are the successors to the P7, PFD7, C7, CFD7, G7 and S7 product families”, according ...
