Power-up current control #55

Closed sacidu93 closed 6 years ago

sacidu93 commented 7 years ago

When a rectified high voltage DC is applied to the STMBL in his actual topology, a very large inrush current will result to charge the on-board big capacitor, this may damage the rectifier diodes and/or PCB tracks ( and power connectors sometimes). An inrush current control circuit is highly recommended on STMBL board ( if it's not yet implemented on the rectifier side ), this can be a simple resistor which will be bypassed by a relay switch when the capacitor voltage reaches two-thirds of DC bus voltage.

This is implemented in the supply module: https://github.com/rene-dev/stmbl/tree/master/hw/kicad/rectifier
