Allegro MicroSystems launches high-bandwidth current sensor technology to help enable high-performance power conversion

 


【Lansheng Technology News】Allegro MicroSystems has announced the launch of new high-bandwidth current sensors ACS37030 and ACS37032 that enable higher performance power conversion using GaN and SiC technologies in electric vehicles, clean energy solutions and data center applications.


Current high power density GaN and SiC FET charging and power infrastructure requires high speed, low loss devices to ensure efficiency and reliability. Existing current sensing solutions have limited operating range and require additional components and a larger bill of materials (BOM) in the design, adding size and weight to the application.


To address these challenges, Allegro has launched two high-bandwidth current sensor products, ACS37030 and ACS37032, which are optimized to provide high efficiency and performance while reducing design time and board space. They employ a dual signal path approach, with one path capturing low-frequency DC current using Hall effect components and the other capturing high-frequency current data through an inductor coil.


Allegro's latest current sensor has a more compact design, higher efficiency and lower cost, suitable for high-frequency switching in power systems, and brings the following advantages to designers:


  • Manage the thermal conditions of high switching frequencies and high voltages and currents efficiently and quickly: providing fast response times, providing critical protection and improving efficiency by reducing energy loss and consumption.
  • Able to achieve stable and safe control and reduce electromagnetic interference: the temperature sensitivity error is only 2%, and the inductor coil characteristic curve increases the signal-to-noise ratio (SNR) with increasing frequency, thereby reducing noise and simplifying electromagnetic compatibility.
  • Reduce design footprint and achieve system reliability and protection: Using a compact and efficient fuse-lead SOIC-6 package, it can withstand harsh automotive and industrial environments and achieve high reliability and protection functions.
  • Balancing cost considerations and reducing design complexity: Simplifying designs and promoting easy-to-design, cost-optimized, high-power, high-frequency switching power conversion for GaN and SiC devices.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
