A variable force solenoid (VFS) is an electro-hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on-board controller of a powertrain. A low flow VFS is used as a signal level devices for transmission line pressure control or application of clutches.
The rotary solenoid is an electromechanical device used to rotate a ratcheting mechanism when power is applied. These were used in the 1950s for rotary snap-switch automation in electromechanical controls. Repeated actuation of the rotary solenoid advances the snap-switch forward one position.
A direct-acting solenoid valve typically operates in 5 to 10 milliseconds. Pilot-operated valves are slightly slower; depending on their size, typical values range from 15 to 150 milliseconds. [2] Power consumption and supply requirements of the solenoid vary with application, being primarily determined by fluid pressure and orifice diameter.
The starter motor is a series, compound, or permanent magnet type electric motor with a solenoid and solenoid operated switch mounted on it. When low-current power from the starting battery is applied to the starter solenoid, usually through a key-operated switch, the solenoid closes high-current contacts for the starter motor and it starts to ...
Low-power switch-mode power supplies (cell phone charger, standby power supply in PCs) Low-cost multiple-output power supplies (e.g., main PC supplies <250 W [ citation needed ] ) The flyback converter is commonly used at the 50 to 100 W power range, as well as in highvoltage power supplies for televisions and computer monitors - Fundamentals ...
A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC power supply. The distinguishing feature of a push-pull converter is that the transformer primary is supplied with current from the input line by pairs of transistors in a symmetrical push-pull circuit. The ...
A resonant converter is a type of electric power converter that contains a network of inductors and capacitors called a resonant tank, tuned to resonate at a specific frequency. They find applications in electronics, in integrated circuits. [1] There are multiple types of resonant converter: Series resonant converter [2] Parallel resonant converter
