The extremely environment friendly and rugged transfer-moulded modules simplify compact motor drive design for functions together with followers and pumps
Introducing the brand new, built-in, converter-inverter-power issue correction (PFC) modules NXH50M65L4C2SG and NXH50M65L4C2ESG which can be appropriate to be used in industrial motor drives, servo drives and HVAC the place they’re used to drive motors for functions together with followers and pumps.
The NXH50M65L4C2SG and NXH50M65L4C2ESG are transfer-moulded energy built-in modules (TMPIM) primarily based upon customary aluminium oxide (AI2O3) substrate and enhanced low thermal resistance substrate respectively. Ideally suited to rugged industrial functions with excessive output energy, the modules include a converter−inverter−PFC circuit, which consists of a single-phase converter with 4 75 A, 1600 V rectifiers. The three-phase inverter makes use of six 50 A, 600 V IGBTs with inverse diodes.
The twin−channel interleaved PFC includes two 75 A, 650 V PFC IGBTs with inverse diodes and two 50 A, 650 V PFC diodes. An embedded NTC thermistor permits machine temperature monitoring throughout operation.
Because the module is pre-assembled in an optimised format and configuration, parasitic components are very small compared with discrete PCB-based designs, thereby permitting a large PFC switching frequency vary between 18 kHz and 65 kHz. The extremely environment friendly NXH50M65L4C2SG and NXH50M65L4C2ESG are rated at 50 A to be used in functions as much as 8 kW.
Accessible in a compact transfer-moulded DIP-26 bundle, the modules measure simply 73 mm x 47 mm x 8 mm – a 20 per cent space financial savings over present options, enabling increased ranges of energy density. The sealed and strong bundle consists of an built-in heatsink (with 6 mm clearance to pins) and affords excessive ranges of corrosion resistance. A silicon carbide (SiC) choice can also be accessible for additional elevated switching frequency and effectivity.
The brand new NXH50M65L4C2SG and NXH50M65L4C2ESG work alongside the FAN9672 PFC controller and gate driver options together with units within the new NCD5700x household. The lately launched NCD57252 twin channel remoted IGBT/MOSFET gate driver affords 5 kV of galvanic isolation and might be configured for twin low-side, twin high-side or half-bridge operation. The NCD57252 is housed in a small SOIC-16 wide-body bundle and accepts logic stage inputs (3.3 V, 5 V & 15 V). The excessive present machine (supply 4.0 A / sink 6.0 A at Miller plateau voltage) is appropriate for high-speed operation as typical propagation delays are 60 ns.
Driving motors in essentially the most environment friendly method is vital to simplifying set up, decreasing warmth build-up, enhancing reliability in addition to decreasing system prices. The ON Semiconductor TM-PIM units standardise the pinout with minimised parasitic to present designers a excessive efficiency ‘plug and play’ answer. Coupling the NXH50M65L4C2SG and NXH50M65L4C2ESG with FAN9672 and NCD57252 gives a fast design path to classy and environment friendly motor management options.
