2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   An inverter may produce a square wave, sine wave, modified sine wave, pulsed sine wave, or near-sine pulse-width modulated wave (PWM) depending on circuit design. Common types of inverters produce square waves or quasi-square waves. One measure of the purity of a sine wave is the total harmonic distortion (THD). [4]

3. Automobile auxiliary power outlet - Wikipedia

   en.wikipedia.org/wiki/Automobile_auxiliary_power...

   An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet [1]) in an automobile was initially designed to power an electrically heated cigarette lighter, [1] but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the ...

4. Resonant inverter - Wikipedia

   en.wikipedia.org/wiki/Resonant_inverter

   This type of inverter produces an approximately sinusoidal waveform at a high output frequency, ranging from 20 kHz to 100 MHz, and is commonly used in relatively fixed output applications, for example, induction heating, sonar transmitters, fluorescent lighting, or ultrasonic generators. Due to the high switching frequency, the size of the ...

   If more than two voltage levels were available to the inverter output terminals, the AC output could better approximate a sine wave. [17] For this reason multilevel inverters, although more complex and costly, offer higher performance. [18] A three-level neutral-clamped inverter is shown in Figure 10.

6. AITO M9 - Wikipedia

   Developed in collaboration with Harmony Intelligent Mobility Alliance (HIMA), the M9 is equipped with many technologies from Huawei, such as the HarmonyOS intelligent cockpit and the Huawei ADS 2.0 (ADS 3.0 Since 2024), which is an AI-powered advanced driver assistance system (ADAS) consisting of one Lidar, three millimetre wave radars, 12 ...

7. Korail Class 1000 - Wikipedia

   en.wikipedia.org/wiki/Korail_Class_1000

   On May 1, 2010, train 1-58 was wrecked in a collision with Class 311000 train 311-74 (which was known as Class 5000 train 5-75 at the time of the collision). Car 1158 suffered significant damage while other cars behind it received minor damage. [4] The whole train was retired and most cars were scrapped shortly after. [d]

8. Variable-frequency drive - Wikipedia

   en.wikipedia.org/wiki/Variable-frequency_drive

   Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

9. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...
