Chopper and PWM[edit]

Is a chopper a specialized application of Pulse-width modulation? Sylvain Leroux (talk) 10:18, 5 August 2011 (UTC)[reply]

No, not as a rule. A chopper is a device, while PWM is a modulation method. But there is a connection, you've seen that right. In many applications choppers are controlled by a pulse-width modulated signal. Jaho (talk) 09:45, 16 December 2011 (UTC)[reply]

What other method would a chopper use, besides PWM? If it's chopping the input to vary the power, isn't that the definition? Amillar (talk) 20:02, 23 January 2013 (UTC)[reply]

Chopper Stabilized Driver

An entry for "chopper stabilized [stepper] drivers" might be interesting. That is one of the more common uses today. Jbottoms76 (talk) 04:19, 29 July 2012 (UTC)[reply]

Query the opening statement that the term "chopper" is much less used nowadays[edit]

The word "chopper" is used freely in "Electric Motors and Drives" by Austin Hughes (of the University of Leeds, UK), pub Newnes, 3rd edition 2006.UBJ 43X (talk) 18:12, 3 August 2012 (UTC)[reply]

Suggested split[edit]

User:Stündle has suggested splitting the section "Chopper amplifiers" into a separate article - I'm inclined to agree (the section is clearly about the amplifier, rather than the circuit), although I'd also consider merging to Amplifier#Other amplifier types as an alternative. Bring it here for discussion. Yunshui 雲‍水 08:38, 4 January 2013 (UTC)[reply]

Chopper amplifiers are a type of electronic amplifiers. At least today. Further this topic has enough substance for an own article, see de:Chopper-Verstärker.

What is K1 on the schematic?[edit]

What is K1 on the schematic? 69.77.198.143 (talk) 22:41, 22 January 2023 (UTC)[reply]

Proof that Wikipedia articles are only written to amuse editors and not to instruct the unknowing. It's a vibrator - a pair of physical electrical contacts opened and closed automatically at some convenient rate, whihc hopefully is described in the linked article. --Wtshymanski (talk) 19:56, 23 January 2023 (UTC)[reply]
