2. EcoFlow - Wikipedia

   en.wikipedia.org/wiki/EcoFlow

   EcoFlow’s smart devices, like the GLACIER portable refrigerator [19] and WAVE 2 air conditioner, are designed for off-grid cooling and climate control, offering convenience for outdoor or remote use.

3. 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]

4. Inverter compressor - Wikipedia

   en.wikipedia.org/wiki/Inverter_compressor

   In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.

5. 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 ...

6. Alternating current - Wikipedia

   en.wikipedia.org/wiki/Alternating_current

   The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa (the full period is called a cycle). "Alternating current" most commonly refers to power distribution, but a wide range of other applications are technically ...

7. Variable-frequency drive - Wikipedia

   en.wikipedia.org/wiki/Variable-frequency_drive

   Solutions to overvoltages caused by long lead lengths include minimizing cable length, lowering carrier frequency, installing dV/dt filters, using inverter-duty-rated motors (that are rated 600 V to withstand pulse trains with rise time less than or equal to 0.1 microsecond, of 1,600 V peak magnitude), and installing LCR low-pass sine wave filters.
