DC Chopper or DC to DC Converter - Working Principle

Web(c) A separately excited DC motor of 10 hp, 200 V, 1750 rpm is fed from a DC-DC chopper for speed control purpose. The motor has armature resistance r a = 0.25Ω and the series inductance is such that the motor current is flat and continuous. The chopper is fed from a 450 V D C source. The schematic diagram is shown in the figure below. WebIn 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 … WebThe chopper-fed motor is, if anything, rather better than the phase-controlled, because the armature current ripple can be less if a high chopping frequency is used. Typical waveforms of armature voltage and current are shown in Figure 1 (c): these are drawn with the assumption that the switch is ideal. A chopping frequency of around 100 Hz, as ... thebuddepo.net
