    PSDcast – Resilience Drives a Renewed Focus on Energy Storage

    Alex Stapleton, CCO at Alexander Battery Technologies

    ­As renewable energy like wind and solar has become more prominent, energy storage has become ever more critical. But recent incidents like the large-scale blackout in Spain and the recent one in L.A. have shifted the way companies view battery storage – for renewable energy and for business in general. And on

    Figure 1. The concept of Burst Mode in a switch-mode power supply.

    ­Even switch-mode power supplies with a fixed switching frequency do notalways show a continuing pattern of pulses. In some conditions, pulses areomitted for various reasons. This is important to consider for output ripplevoltageand EMI effects. A switching regulator for voltage conversion normally operates

    8 EV Challenges of Converting High Voltage to SELV

    Click image to enlarge

    Figure 1: Sine Amplitude Converter (SAC) power modules, like the BCM6135, can be used in place of regulated DC-DC converters to reduce size and for higher efficiency. BCM6135 bench measurement efficiency at 25°C shows a peak efficiency around 97.5% at half load

    The shift to 800V electric vehicle (EV) battery architectures is inspired by the need to increase charging rates, reduce resistive losses (I2R), and improve drivetrain efficiency. In parallel, zonal electrical architectures are emerging, using 48V local buses to reduce harness weight. Converting 800V high-voltage (H
