In this small project we will be having a closer look at appliances that require a softstarter in order to properly work with a limited output current system. The shown appliances in this project include an inverter, a boost converter, a power supply and a motor. We will find out why a big inrush current requires a softstarter and how we can build a simple circuit that can do this job. Let's get started!
