A 3-port solenoid-type boost controller A 4-port solenoid-type boost controller (used for a dual-port wastegate) The purpose of a boost controller is to reduce the boost pressure seen by the wastegate's reference port, in order to trick the wastegate into allowing higher boost pressures than it was designed for.

The EMD AEM-7 is a twin-cab four-axle 7,000 hp (5.2 MW) B-B electric locomotive built by Electro-Motive Division (EMD) and ASEA between 1978 and 1988. The locomotive is a derivative of the Swedish SJ Rc4 designed for passenger service in the United States .
On eBay, the bidding price started at $233.95, with bidding ended at a sale price of US$10,000. [63] Both the e-mail exchange and the picture have become internet hits. [64] In July 2009, Dornoch Capital Advisors placed England's Coca-Cola League One Side Tranmere Rovers F.C. on eBay without permission from owner and chairman Peter Johnson ...
This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions.
The input is left side, the output with load is right side. The switch is typically a MOSFET , IGBT , or BJT transistor A buck converter or step-down converter is a DC-to-DC converter which decreases voltage , while increasing current , from its input ( supply ) to its output ( load ).
The boost/buck capabilities of the SEPIC are possible because of capacitor C1 and inductor L2. Inductor L1 and switch S1 create a standard boost converter , which generates a voltage ( V S1 ) that is higher than V IN , whose magnitude is determined by the duty cycle of the switch S1.
In the field of control engineering, a map-based controller is a controller whose outputs are based on values derived from a pre-defined lookup table. [1] The inputs to the controller are usually values taken from one or more sensors and are used to index the output values in the lookup table. [ 1 ]
An implementation is described in a whitepaper by Zilog on an ebike hub motor controller [5] for a 200 W, 24 V brushless DC electric (BLDC) motor. [6] P.A.S or PAS may appear within the list of components of electric conversion kits for bicycles, which implies Pedal Assistance Sensor or sometimes Pulse Pedal Assistance Sensor. Pulse usually ...
