PWM works by repeatedly turning power off & on at the desired rate so that the average power can be a specific % of the available power. For PWM vapes that means if you have 8V batteries running with 50%, how have an average of 4V, 75% would be an average of 6V. By adjusting the on/off ratio up or down you can get almost any effective power.

What is a PWM vape?
I'll start this of by say that a PWM vape is the simplest of the regulated type vapes that allows you to adjust how much power goes to your coil. While it's nice to be able to fine tune it does have it's disadvantages such as it may need adjusting as your batteries drop and any time you change your coil.
What is variable wattage vaping mode?
The variable wattage vaping mode makes it easy. When you use your mod’s variable wattage mode, your device may also offer selectable preheating strengths such as “Soft,” “Normal” and “Hard.” The preheating strength controls how quickly the device reaches the target wattage.
What is the Smart vaping mode?
The smart vaping mode is a proprietary feature that varies from device to device, so the implementation of this mode will vary. In some cases, a vape mod’s smart mode will cause the device to check the resistance of the attached tank and automatically suggest an appropriate wattage.
What is a vape mod?
Customizable coils and tanks: If you’re vaping concentrate material, a vape mod offers a highly personalized experience. A component like a coil can be swapped out at will (provided it’s compatible with the specific device you’ve chosen).
What is the benefit of using PWM?
The benefit of using PWM is the ability to regulate the time that the circuit is on vs off or vice-versa. A good comparison of this is an LED light with adjustable brightness.
Why does my mod whine or buzz?
Electronic switching is noisy in all applications, especially when unfiltered. The frequency in which most boards run is within the audible range for most humans.
Why wont my voltmeter read correctly?
Mainly this is due to the oscillation of the voltage, voltmeters generally want a flat input voltage and not one that is oscillating many times per second.

I can't get into the specs like you want, but the attraction for many is that PWM can be made cheaply by just about anyone that can handle a soldering iron.

Once upon a time, vape mods using a syncronous rectifier were a rarity. A Schottky diode was mostly used, but with a great toll on efficiency.

How so? The board puts out the current voltage level of the batteries, there is no buck or boost.
What is a vape mod?
Vape mods include functionality that is supposed to enhance vapor flavor, quality, and production. Basically, if you want bigger clouds with more flavor, a vape mod might be the right device for you. These devices do present a more significant learning curve than the simpler alternatives, however, so it’s important to fully understand their ...
What is an advanced vape?
As the word “advanced” suggests, these types of devices are only recommended if you are already familiar with vaping and want to kick things up a notch with a more customizable device.
What is enhanced vapor flavor?
Enhanced vapor flavor: In addition to the denser clouds you can expect from a box mod, many advanced portable vaporizers offer enhanced vapor flavor as well. Vape mods are renown for their ability to promote the most flavorful experience.
What kind of batteries do vaporizers use?
Most portable vaporizers rely on standard 18650 lithium-ion batteries. Vape mods can support larger batteries, including the 20700, 21700, and 26650 batteries. These batteries put out more power than their smaller cousins, allowing for long-lasting performance and powering boosted vapor production.
How many watts does a box mod use?
To create dense clouds of vapor with cannabis concentrates, a box mod should at least put out about 150 watts. A higher wattage will drain your battery more quickly, but the overall battery life is related to the milliamp-hour (mAh) rating of your battery.
What does wattage mean in a battery?
Wattage: Wattage refers to the electrical power your battery is capable of outputting to the heating element in your device. In general, the higher the wattage, the higher the vapor production, though the true result depends on several other factors as well.
When will vape mods be available?
Aug 1, 2019. You’ve likely come across the term “vape mod” while researching vaporizers, although vape mods are less common in the world of cannabis vaporizers. These advanced devices typically grant more personalized control over your sessions but there is a significant learning curve to use them properly.

I'm trying to understand the more technical part of vaping, something I never really thought too much about but since I'm 'flavor' chasing and whatnot, I figure I'd look into it.

I don't think hardly any people on these forums would have the equipment necessary to measure the difference in heat/vapor production from a pulse/lower frequency mod vs high frequency. I have an IR camera, but it's not fast enough to see change in heat in a 33.3 times per second.
Lessifer Vaping Master Verified Member ECF Veteran
Here's how I understand it. A regulated device that uses PWM fires the coil alternating between 6v and 0v for varying lengths of microseconds to average out at whatever voltage you have it set to. The lower end devices, that uses the 33.3 chip, do this 33.3 times per second.
What does PWM stand for in CPU?
A Basic Definition. By Scharon Harding December 12, 2018. PWM stands for pulse width modulation. PWM fans and/or pumps are found in some CPU coolers and GPU (aka graphics card) coolers. They use an integrated circuit to control the speed of a fan or pump and, therefore, how much cooling it’s providing to the CPU or GPU.
How does a PWM fan work?
PWM fans works in correlation with the motor, receiving full power or zero power. (Image credit: EKWB) PWM is also used in servo motors, voltage regulation, telecommunications and audio equipment. This article is part of the Tom's Hardware Glossary. Further reading:
How many PWM headers are there on a motherboard?
Most mainstream motherboards have at least one 4-pin PWM header, and the best motherboards usually have to four to six. Note, older fans may use 3-pin connectors. PWM works like a switch, turning on and off while controlling the level of power delivered to the fan or pump.
How does PWM work?
PWM works by pulsating DC current, and varying the amount of time that each pulse stays ‘on’ to control the amount of current that flows to a device such as an LED. PWM is digital, which means that it has two states: on and off (which correspond to 1 and 0 in the binary context, which will become more relevant to you if using microcontrollers).
Why are PWM circuits so efficient?
The key reason that PWM circuits are so efficient is that they don’t try to partially restrict the flow of current using resistance. They turn the current fully on and fully off. They just vary the amount of time that it is on instead. PWM LED Dimmer Circuit Example.
What is pulse width?
Pulse Width Modulation (PWM) is a nifty current control technique that enables you to control the speed of motors, heat output of heaters, and much more in an energy-efficient (and usually quieter) manner. Existing applications for PWM include, but are not limited to: 1 Variable speed fan controllers. 2 VRF HVAC compressor drives. 3 Hybrid and electric vehicle motor drive circuits. 4 LED Dimmers.

What does 0% mean in PWM?
A PWM duty cycle of 0% means that the power is off. In such a state, an LED would not be operational. It would simply be off. PWM signal (square wave) with a duty cycle of 0%. This means the power is off.
How does a tiny power source work?
The tiny power source controls the large one with the help of power transistors. The tiny one generates the signal , and the ‘ power ‘ which is the large current and voltage that actually power on the LED is controlled by the aforementioned transistors.
