4500-V IGBT gate driver supports high-power modules from major manufacturers Amantys has launched a new Insulated Gate Bipolar Transistor (IGBT) Gate Driver for high power modules, operating at 4500 V with current ratings from 400 A to 1200 A, designed to support modules from manufacturers including ABB, Dynex, Hitachi, Infineon and Mitsubishi. The IGBT gate driver includes the Amantys Power Insight condition monitoring hardware and software subsystem, to observe and report critical power switching characteristics. Building on the philosophy of ‘Power Simplified by Design’, the unit is fully integrated and can measure and export critical performance parameters over the existing PWM and fault interface to simplify the design-in process. The 4.5kV gate drive meets requirements of growing high voltage IGBT market in locomotive, wind turbine, high voltage DC and industrial drive applications. Amantys www.amantys.com MCU packs 204MHz ARM Cortex-M processors with 80MSps 12-bit ADC The LPC4370 microcontroller from NXP Semiconductors forms a complete solution for high-speed data acquisition applications. Powered by a 204-MHz ARM Cortex- M4 processor, the LPC4370 also features the a 12-bit ADC capable of sampling at 80MSamples/s. In addition, the LPC4370 has a 204-MHz Cortex-M0 co-processor for offloading control and I/O tasks like handling USB stacks, as well as a dedicated subsystem for handling programmable digital I/O and pre- or post-processing. Advanced peripherals include Hi-Speed USB with on-chip PHY and Ethernet for high-speed communications, and a graphics LCD controller for display interfacing. Demanding data acquisition applications such as spectrum analysis, current measurement, digital signal processing, audio streaming / processing, and analytical instrumentation typically require multiple chips for input, processing and output. The LPC4370 integrates this functionality in a single chip, eliminating data bottlenecks, improving power efficiency and noise performance, as well as reducing the overall PCB footprint, cost and application complexity. The multicore architecture of the LPC4370 also offers simplified algorithm partitioning. With its large SRAM and flexible memory expansion, the LPC4370 allows system designers to tailor the memory type and size to their specific application requirements. NXP Semiconductors www.nxp.com Online automated battery sizing calculator supports off-grid renewable energy applications Trojan Battery has developed an automated battery sizing calculator to accurately size a battery bank for renewable energy applications. Trojan’s battery sizing calculator is designed to simplify the task of properly sizing a battery bank for off-grid renewable energy systems. A battery bank is a vital component of a system, so careful attention must be paid to battery sizing to ensure maximum battery performance and longevity. Three factors must be considered when sizing battery banks for renewable energy systems: the electrical power required, or load, of a particular application, the maximum depth of discharge (DOD) the battery will be allowed to go down to and the autonomy desired, or the number of days the battery will be used to power the loads. Customers simply fill in the appropriate information on the electronic form such as battery voltage, desired to depth-of-discharge (DOD), days of autonomy, AC and DC loads, device types with power ratings, and hours per day or days per week used, and the application automatically determines the required battery capacity. It then recommends the Trojan battery models for their particular set up. The calculator also allows customers to run ‘what if’ scenarios to find specific battery options to meet their budget or configuration requirements.
