iirc (been awhile since EE so could be wrong):
Dynamo is basically an AC gen with some crap in front to make output look DC.
"Pulsing DC current" is actually ac with >50% of the duty cycle zeroed out.
Again, could be very wrong here my memory is fuzzy as hell.
- y4mi 10y agowikipedia seems to agree with you, if i read this right. > A dynamo is an electrical generator that produces direct current with the use of a commutator. >> A commutator is a moving part of a rotary electrical switch [...] that periodically reverses the current direction between the rotor and the external circuit
- dredmorbius 10y agoIf I'm remembering and understanding correctly: the commutator swaps the + and - ends of the energised coil. So you're not actually zeroing out the inverted end of the wave, you're swapping its connections to the circuit. Where an AC generator coil applies a positive and negative voltage to a single lead, the DC generator swaps leads as the current reverses. I'm glad I'm not the only fuzzy one here....
