2. Pulse-width modulation - Wikipedia

   en.wikipedia.org/wiki/Pulse-width_modulation

   Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an

3. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   Switched-mode power supplies are used for DC-to-DC conversion as well. In heavy vehicles that use a nominal 24 V DC cranking supply, 12 V for accessories may be furnished through a DC/DC switch-mode supply. This has the advantage over tapping the battery at the 12 V position (using half the cells) that the entire 12 V load is evenly divided ...

4. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   This small device allowed the dimmer to be installed in a standard electrical wall box while saving energy. [2] [3] In 1966, Eugene Alessio patented a light bulb socket adapter for adjusting a light level on a single light bulb using a triac. To house this device, he decided on a 2-inch round device with one end capable of being screwed into a ...

5. Chopper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Chopper_(electronics)

   Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors.

6. PWM rectifier - Wikipedia

   en.wikipedia.org/wiki/PWM_rectifier

   PWM rectifier (Pulse-width modulation rectifier) is an AC to DC power converter, that is implemented using forced commutated power electronic semiconductor switches. Conventional PWM converters are used for wind turbines that have a permanent-magnet alternator. [1] Today, insulated gate bipolar transistors are typical switching devices.

7. SAE J3068 - Wikipedia

   en.wikipedia.org/wiki/SAE_J3068

   Also, SAE J3400 electric vehicles in North America are required to support power transfer under PWM-CP at 277 VAC. [ 6 ] Under SAE J3400 and SAE J3068 EVSE cannot use PWM-CP controls when nominal system voltages exceed 480Y/277 VAC (single-phase 277 VAC). digital communication (e.g. LIN-CP) shall be used when these voltage limits are exceeded ...

9. DMX512 - Wikipedia

   en.wikipedia.org/wiki/DMX512

   Typically a dimmer has a starting address that represents the lowest-numbered dimmer in that pack, and the addressing increases from there to the highest-numbered dimmer. As an example, for two packs of six dimmers each, the first pack would start at address 1 and the second pack at address 7. Each slot in the DMX512 packet corresponds to one ...
