The most demanding applications require single digit, part per million temperature drift, subppm linearity, and low, predictable noise performance. The circuit shown in Figure 1 is a […]

12VDC to 220-380VDC Converter


https://www.electronics-lab.com/12vdc-to-220-380vdc-converter/

When powering many appliances from a sine wave inverter, the HV DC is converted to AC only to be rectified back to DC in the appliance. This inverter eliminates the SPWM stage and outputs DC only. This DC can be used to power appliances, or as a HV DC source for your SPWM, variable frequency […]

Free Elektor Project: Inrush Current Limiter (Soft Starter) for AC and DC Loads


https://www.electronics-lab.com/free-elektor-project-inrush-current-limiter-soft-starter-for-ac-and-dc-loads/

Inrush current/Switch-ON surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Inrush current is much higher than the load’s steady-state current and that’s the source of many problems such as fuse blowing up, load failure, load’s lifetime reduction, sparks at the switch contacts … etc. The figure below […]
