2018年5月23日 · A sine wave is a repetitive change or motion which, when plotted as a graph, has the same shape as the sine function. A quote more directed to electronics: The electrical power in your house is AC or Alternating Current.

2012年3月20日 · The average value would be equal to zero as the positive and negative halves will cancel each other out if the average value is calculated over the full cycle in a pure sine wave. In the image below, the average or mean value of an AC waveform is calculated or measured over a half cycle.

2021年8月24日 · The idea, if I understand correctly, is that the sine wave filter smoothes the output, eliminating the spikes at the edges of the PWM pulses. I'm installing a variable frequency drive in a setting where I have a very well insulated short length of cable. The specifications in the VFD manual do not suggest I am close to needing a sine wave filter.

2015年9月23日 · At the secondary of HF transformer is a rectifier with caps and you get the HV DC voltage. The second stage is H-bridge with sine wave PWM that has to have an output lowpass LC filter to filter out high frequency. 2. DC voltage is inverted with sine wave PWM, then filtered with lowpass LC filter, then a classical step up transformer.

2018年2月17日 · Just model the circuit with with highest and lowest loads and see what happens to the shape of the sine wave and its amplitude. I'd consider starting with L = 10 mH and C = 3.3 uF (876 Hz) with a little series resistance with the inductor to …

2016年12月1日 · Maximum slope of a sine wave. Ask Question Asked 8 years, 4 months ago. Modified 8 years, 4 months ago.

2021年11月3日 · Sine wave with an additional square wave output; All controls use a single encoder with a built-in button; Very low power consumption suitable for 3xLR44 batteries operation; Extremely low power consumption in Off state (0.8 uA) eliminating the need for a physical switch (Note 1) Using a single SLG47004 IC

2015年4月6日 · I need to transform a bipolar sine wave (varies from -5 V to 5 V, 1 kHz) to a square wave for further digital processing (0 to 3.3 V), as in this image: The important thing is that this sine wave can't be distorted, so there can't be any limiting diodes at the input. I have got only 3.3 V and 5 V voltage supplies.

2015年2月5日 · \$\begingroup\$ @Random832 No, sine wave input to a passive R-C-L network always gives sine wave output (attenuated & phase shifted by a different amount depending on frequency.) To see why, see the mechanical resonance shown in Andy Aka's answer, of which electrical resonance is a direct analogue.

2016年9月6日 · Here's the full waveform. It's monotonic and the distortions are much less obvious. Note that the voltage here is 122 Vrms with a peak of about 165 V, slightly above the nominal range. Both this and the household mains show a peak voltage that's lower than what we'd expect for a pure sine wave with the measured RMS value. Here's the FFT.
