Infineon is aiming to drive motors up to 4kW with a series of integrated three-phase IGBT motor drivers. There are three: IM12B10CC1 800V 10A 2.2kW IM12B15CC1 800V 15A 3kW IM12B20EC1 800V 20A 4kW Each comes in the same 36 x 23mm DIP package and includes six 1,200V IGBTs, six anti-parallel diodes, and a protected level-shifting gate driver compatible with logic-level ...

Emis has created a range of three phase, dual stage EMC filters designed for industrial motor and drive systems across 5 to 170kW. TMF3221 and TMF3222 “are housed in a space-saving slim book-shelf enclosure which may be installed next to inverters, converters or motor drives”, according to the company. “The devices are designed to meet the needs of power drive ...

Cosel has introduced a 3.5kW ac-dc 1U rack-mount power supply that will run from three phases between 180 to 528Vac. Two versions are available giving a choice of 48 or 65Vdc output, each trimmable +15% to -50% (24 to 55.2V, or 32.5 to 74.75V). Called HFA3500TF, the enclosed PSUs have three-wire inputs and will run from delta or star power networks. ...

Toshiba is aiming at pumps, air conditioning and fans with through-hole versions of its latest 600V three-phase brushless dc motor drivers. TPD4163K and TPD4164K come in a 32.8 x 13.5 x 3.525mm ‘HDIP30′ package, which has pins on a 1.778mm pitch (Electronics Weekly has asked why this odd pitch was chosen – watch this space). “This new package reduces PCB ...

Infineon has used silicon-on-insulator technology to create a 140V three-phase gate driver for motor drives. Called 6ED2742S01Q, it is designed to drive six external n-channel mosfets using bootstrapping for the upper three, but it unusually includes low-power charge pumps to allow 100% duty cycle high-side operation. For traditional bootstrapped operation, three diodes are monolithically integrated to avoid the need for ...

TDK has introduced six models to its 7.5kW ‘Genesys+’ series of 7.5kW programmable dc power supplies. The new values of 0-30V (250A), 0-60V (125A), 0-80V (94A), 0-200V (37.5A), 0-300V (25A) and 0-1000V (7.5A) slot in between earlier models in the series, introduced in July (see this article for more details). The units need three-phase ac power and there are versions ...

TDK-Lambda is aiming at large industrial distributed power systems with a 45kW non-isolated ac-dc PSU. Called TPF45000-385 it can operate from can operate from 360 – 528Vac three-phase (delta or Y) and produces a stable 385Vdc. Input to ground isolation is 2kVac. Efficiency is up to 98%, allowing air cooling by internal variable speed fans. Operation is across -10 to +50°C ambients (-20°C start-up). ...

TDK-Lambda has introduced 120W and 240W power supplies that run from three-phase across 350 to 575Vac. Called the DRB series, they can deliver a peak of 144W or 288W for two seconds, respectively. Versions are available with outputs of 12V, 24V or 48V. Outputs can be trimmed across 11.4 to 15, 22.5 to 29 or 45 to 56V depending on model. Efficiency is ...

Delta has announced a three-phase 250kW solar string inverter with an input range of 550 to 1,500Vdc “specially designed for huge ground-mounted photovoltaic plants in the upper megawatt range”, according to the company. “Features such as anti-PID and pro-electroluminescence detect problems with PV modules.” Called M250HV, up to 30 dc strings can be connected to its 12 max power point trackers, ...

Panasonic is claiming a world-first for a PCB relay that can be used as the main switching element in three phase systems. Called HE-R, the  35 x 58 x 47mm relay has four normally-open contacts (relay class 4a) that can switch up to 40A at an ambient temperature of +85°C. Update: A UL-compliant two(+one)-pole version was introduced in January 2024 An ...
