I have made a digital dimmer as mentioned in the on semiconductor app note AND0811/D and my purpose is to control a single phase split capacitor motor. and when I connect it to a motor the oscilloscope the waveform is like as shown in MoT.jpg in the attachment. and then i disconnect the motor and connect a light bulb and the waveform as shown in LAMP.jpg in attachment. I didn't connect any noise filter for the system.
can you guys tell me that is this waveforms are normal or erroneous??
is there any harmonics coming when driving the motor?? and if, can anyone suggest me a schematic for filter-out the harmonics??
Thank you..
