New SEMIKRON Modules in Every Power Class for 3-Level Solar and UPS Applications

SEMIKRON, a global leader in the field of power electronics, will be adding 3-level topologies to its product range. 3-level technology boasts a lower distortion factor and consequently reduced filtering requirements. This is a very important feature, especially in applications where a very clear output voltage and output current waveform is needed, e.g. uninterrupted power supply systems (UPS) and solar inverters. The product range will now include MiniSKiiP, SEMITOP and SKiM 4 IGBT modules.

The baseplate-free SKiM4 module is the most powerful IGBT module in the range, with rated currents of between 200A and 600A. As much as 250kVA can be achieved without several modules having to be connected in parallel. SKiM4 modules come in TNPC technology for 650V and 1200V, and 1200V in NPC topology. The modules in TNPC topology can deliver up to 900VDC and 480VAC, while those in NPC topology can push the EU low voltage directive to its limits of 1500 VDC and 1000 VAC.

For smaller currents, baseplate-free, spring-contact IGBT MiniSKiiP modules are available. These modules feature solder-free mounting and are intended for rated currents of between 75A and 200A and reverse voltages of 650V, enabling powers of up to 85kVA. At 4.9A/cm², the power density is very high compared with competitor products, making this module ideal for use in compact systems. A further merit of these modules is the easy single-screw connection between module and heat sink and controller board.

The counterpart to solder-free MiniSKiiP modules is the SEMITOP, an IGBT module which is 12mm in height and soldered on to the Power Circuit Boards and used in applications with current ratings of 20A -150A. These baseplate-free solder-connection modules come in NPC topology and can deliver up to 65kVA. The voltage rating is 600V.

The fact that no solid busbars are needed in SEMITOP and MiniSKiiP modules is the reason for their compact design.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
