CT Sensor on AVR ATmega

A CT (Current Transformers) sensor is a device used to measure alternating current. A CT sensor, like other current transformers is made by a primary winding, a magnetic core and a secondary winding. The primary winding is often a single wire passing through the main core of the transformer. The seconday winding is used to sense the AC current passing through the primary winding wire. They are usually build ...

A simple brushless sensored motor driver for AVR Atmega

Brushless electric motor (BLDC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor. Additional electronics control the inverter output amplitude and waveform (and therefore percent of DC bus usage/efficiency) and frequency (i.e. rotor speed). Because the controller must direct the r ...
