Regenerative Braking Explained

 

Regenerative Braking

Definition

Regenerative braking is a method of slowing down a vehicle by converting its kinetic energy into electrical energy instead of wasting it as heat.

How It Works

Normal Braking: Kinetic Energy → Heat (Lost)
Regenerative Braking: Kinetic Energy → Electrical Energy → Battery

The electric motor acts as a generator and sends energy back to the battery.

Simple Explanation

  • Motor reverses its function
  • Vehicle slows down
  • Battery gets charged

Example

In electric vehicles like Tesla Model 3, releasing the accelerator slows the car and recovers energy back into the battery.

Advantages

  • Saves energy
  • Increases driving range
  • Reduces brake wear
  • Environment friendly

Limitations

  • Less effective at low speeds
  • Cannot fully replace mechanical brakes
  • Depends on battery capacity
Instead of wasting energy as heat, regenerative braking reuses it.

People are good at skipping over material they already know!

DFTs-OFDM vs OFDM: Why DFT-Spread OFDM Reduces PAPR Effectively (with MATLAB Code)

DFT-spread OFDM (DFTs-OFDM) has lower Peak-to-Average Power Ratio (PAPR) because it "spreads" the data in the frequency domain before applying IFFT, making the time-domain signal behave more like a single-carrier signal rather than a multi-carrier one like OFDM. Deeper Explanation: Aspect OFDM DFTs-OFDM Signal Type Multi-carrier Single-carrier-like Process IFFT of QAM directly QAM → DFT → IFFT PAPR Level High (due to many carriers adding up constructively) Low (less fluctuation in amplitude) Why PAPR is High Subcarriers can add in phase, causing spikes DFT "pre-spreads" data, smoothing it Used in Wi-Fi, LTE downlink LTE uplink (as SC-FDMA) In OFDM, all subcarriers can...

Power Distribution in Amplitude Modulation (AM)

Power Distribution In practice, the AM wave s(t) is a voltage or current signal. In either case, the average power delivered to a 1-ohm load resistor by s(t) is comprised of three components: Carrier power = (1/2) A c 2 Upper side-frequency power = (1/8)μ 2 A c 2 Lower side-frequency power = (1/8)μ 2 A c 2 The ratio of the total sideband power to the total power in the modulated wave is therefore equal to μ 2 / (2 + μ 2 ), which depends only on the modulation factor μ. If μ = 1, that is, 100% modulation is used, the total power in the two side-frequencies of the resulting AM wave is only one-third of the total power in the modulated wave. A major topic in Amplitude Modula...

Filter Bank Multicarrier (FBMC)

Filter Bank Multicarrier (FBMC) Filter Bank Multicarrier (FBMC) is an advanced multicarrier modulation technique designed to overcome the spectral inefficiencies and interference issues of OFDM. Motivation: Limitations of OFDM In an OFDM system , the transmitter uses an Inverse Fast Fourier Transform (IFFT) and the receiver uses a Fast Fourier Transform (FFT) to process multiple subcarriers. Each OFDM symbol occupies a duration denoted by T sym . OFDM is a multicarrier modulation technique where a high data-rate stream is divided into multiple parallel low data-rate streams. To mitigate inter-symbol interference (ISI) caused by multipath fading, the total bandwidth B is divided into N narrow sub-bands. However, a major drawback of OFDM is that the subcarrier filters generated by the IFFT/FFT process have poor spectral cont...

OFDM vs SC-OFDM

  The main difference between OFDM and SC-OFDM is that SC-OFDM transmits the signal using a single carrier, while OFDM uses multiple subcarriers. However, in SC-OFDM, the signal is generated with different sub-bands, but it is transmitted through a single carrier (more technically, through a wideband carrier signal). Block Diagram of OFDM: Data → Modulation → Serial-to-Parallel → IFFT → Add CP → Transmit Received Signal → Remove CP → FFT → Parallel-to-Serial → Demodulation → Data Block Diagram of SC-OFDM: Data → Modulation → DFT → IFFT → Add CP → Transmit Received Signal → Remove CP → FFT → Demodulation → Data    In the case of OFDM, the input modulated data is converted from a serial stream to parallel streams, and different subcarriers are assigned to each chunk. Then, IFFT is applied to these chunks, and a cyclic prefix is added to each one. Each chunk is technically referred to as an OFDM symbol . Unlike OFDM, SC-OFDM does not perform serial-to-parallel conversion o...
