Batteries & Other Energy Storage Devices
September 2023
In power supplies, storage inductors play an important role. Unexpected overheating of the magnetic component in the inductors used should be avoided at all costs. The AC losses that are often responsible for this are difficult to estimate. The online simulation tool RedExpert facilitates the development work co

Figure 1. 1,100 mAh alkaline cell, 0.9V cutoff voltage - discharge capacity variation
For consumer electronic devices, battery life is often a critical purchase consideration. Therefore, the fact the calculated battery life of IoT devices is often inaccurate is a significant issue for manufacturers.
One method to measure battery life is to divide the battery capacity in amp-hours by the avera

Figure 1. A bidirectional power supply able to sink and source power. The red line indicates maximum power (30kW) can be sinked at any voltage sweeping from 2000 to 750 V, a feature called autoranging. A conventional power supply could sink maximum power only at 2000 V and 75
Like a programmable power supply in reverse, an electronic load simulates load conditions and measures power consumption.
As end-users demand increasingly efficient devices and longer battery run times, designers increasingly depend on electronic loads. According to MarketsAndMarkets, sales of electroni
