WebNov 12, 1998 · A "chopper" is a mechanism which allows a secondary mirror to be rapidly tilted back and forth. Note that it is notthe secondary itself. Thus a single chopping mechanism could be used with different secondary mirrors. The Keck "IFSM" (for "Infrared Fast Steering Mirror") has both an f/40 secondary mirror and an f/25 secondary mirror … In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to … See more Chopper circuits are used in multiple applications, including: • Switched mode power supplies, including DC to DC converters. • Speed controllers for DC motors See more For all the chopper configurations operating from a fixed DC input voltage, the average value of the output voltage is controlled by periodic opening and closing of the switches … See more Take a general step-up chopper with voltage source $${\displaystyle V_{s}}$$ which is in series with the inductor $${\displaystyle L}$$, … See more One classic use for a chopper circuit and where the term is still in use is in chopper amplifiers.
