Power Integrations Revs Up Motor-Drive Offering With BridgeSwitch-2 BLDC IC Family
BLDC motor hardware-software combo slashes inverter sleep-mode consumption to less than 10 mW, expands output power to 1 HP
Power Integrations (NASDAQ: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today enhanced its hardware- software bundle for brushless DC motors (BLDC) with BridgeSwitch™-2, a new high-voltage integrated half-bridge (IHB) motor-driver IC family targeting applications up to 1 HP (746 W). The new ICs, which feature high- and low-side drivers and advanced FREDFETs with integrated lossless current sensing, deliver inverter efficiency of up to 99 percent. The IHB architecture eliminates hot spots, which increases design flexibility and reliability, slashes component count and saves PCB area. BridgeSwitch-2 is supported by Power Integrations’ MotorXpert™ software suite which includes single-phase trapezoidal control and three- phase sensor-less Field Oriented Control (FOC) modules, speeding inverter development. BridgeSwitch-2 ICs handle operational exceptions in hardware, which permits the use of IEC 60730 Class A safety software, reducing certification time by months. Quiescent BLDC inverters can be ordered into sleep-mode, reducing driver power consumption to less than 10 mW; this leaves more power available under regulated standby power limits to be allocated for loads such as network access and monitoring.

Panasonic Energy presents new nickel metal hydride battery system for railway vehicles at Innotrans fair
At InnoTrans 2024 in Berlin, from September 24 to 27, Panasonic Energy will present, for the first time, its new nickel-metal hydride battery system for railway vehicles at Hall 15.1, Booth No. 180.
The new modular Ni-MH battery system is engineered to provide an auxiliary power supply for railway vehicles, offering a range of features that sets it apart from traditional systems. Key features of the Ni-MH battery system include its compact and scalable design, allowing for flexible mounting on vehicles. This not only saves space but also contributes to improved efficiency and performance. Additionally, the system boasts a long lifespan, reducing the need for frequent replacements and minimizing downtime.
Maintenance-free and equipped with a remote monitoring function, the Ni-MH battery system enables easy diagnosis and monitoring, enhancing operational reliability and safety. Furthermore, it eliminates the need for electrolyte refilling, offering a hassle-free solution for railway operators. If desired, the system can also replace an existing battery system running on Nickel Cadmium batteries. Speaking about the new Ni-MH battery system, Panasonic Energy Division Head Mr. Oliver Sonnemann expressed enthusiasm about the potential impact of the modular system. “We are proud to introduce our advanced Ni-MH battery system for railway vehicles at the Innotrans fair. This system highlights our dedication to developing sustainable and efficient solutions for the transportation industry. We believe it will enhance the performance, safety, and environmental footprint of railway operations.”

Pickering doubles power ratings, expanding high-spec options for popular reed relays
New 50-100% higher power ratings for four of Pickering’s most popular relay series, the 112, 113, 116 & 122 Series
Leading manufacturer of high performance reed relays, Pickering Electronics has increased the power ratings of four of its most popular relay series – including Series 112, 113 and 116, plus ultra-high density 4mm2 Series 122 – to ensure engineers have more options for higher switching specifications, without taking up more valuable PCB space. As part of the company’s ongoing commitment of continuous innovation and product improvement, the higher power ratings enhance the already wide range of switching options available. With thousands of versions on offer, as well as customisable options and bespoke relays to fit any application need, engineers have more flexibility than ever before.
Series 112 The Series 112 single-in-line (SIL) reed relays, requiring a board area of only 0.15 inches (3.8mm) by 0.4 inches (10mm), now feature a new general purpose switch type 1 option, rated for up to 20 Watts (15 W for the 3 V coil version) at 1 Amp switching current (with 1 Amp carry current). The small footprint in this relay is achieved by mounting the reed switch diagonally within the package. The Series is suitable for high-density card-based systems such as VME, VXI, CompactPCI, and PXI. The high-quality, sputtered ruthenium switch contacts also make them ideal for ATE (automatic test equipment).

NeoMesh wireless sensor networks enable easy monitoring of remote Australian farm assets
NeoCortec, the experts on wireless connectivity and providers of ultra-low-power bi-directional wireless mesh network hardware and software solutions, is working together with Australian company farmIT to enable easy monitoring of remote Australian farm assets like livestock water troughs, boundary gates, water tanks, diesel tanks, rainfall, etc. Neocortec’s ultra-low power, scalable and easy-to-install wireless mesh network technology simplifies installation and reduces operational costs for Australian farmers dramatically. “The labor- intensive process of manually checking livestock water supplies and other farm assets can be prohibitively expensive. NeoMesh presents a low-power, cost-effective solution perfect for the scale of Australian farms,” says Luke Mitchell, CEO of farmIT. farmIT’s system uses NeoCortec’s long-range radio modules integrated with sensors on each watering point, efficiently channelling data to a central hub. This data is then transmitted to the cloud via an existing internet connection, completely eliminating the need for any costly communication network. Remarkably, the sensors operate on just two AA batteries for up to five years and the mesh network means that the distance covered is effectively unlimited. With the long-range-radio modules, farmIT is able to get a range of up to five kilometers when there is a clear line of sight. And, if for whatever reason the range to the next node is not enough, a relay station is simply put in the middle to extend the range. But farmIT’s sensor solutions not only monitor livestock water troughs, but also boundary gates, water tanks, diesel tanks, rainfall, soil temperature, etc.
