This 50A PWM DC motor controller use one chip TL494, 3 MOSFETS and Diode 30A. The TL494 incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. The TL494 contains two error amplifiers, an on-chip adjustable oscillator...
For AC brushed motor speed control is most commonly used triac phase switching. According to the degree of the opening of the triac, we can control engine speed. But this applies only without load. With increasing load speed also decreases, until in extreme cases can also stop the engine...
The UCC3626 motor controller device combines many of the functions required to design a high-performance, two- or four-quadrant, three-phase, brushless dc motor controller into one package. Rotor position inputs are decoded to provide six outputs that control an external power stage. A precision triangle oscillator and latched comparator provide PWM motor control in either voltage- or current-mode configurations.
This article is for those who want to make their own car amplifier. The basics of calculation will be discussed below. If you have understood it you will be able to make car amplifier yourself. The design of this car amplifier is based on Kenwood car amplifier KAC-718 for subwoofer with maximum power output of 240W (4ohm, at 100Hz).
The MC33035 is a high performance second generation monolithic brushless DC motor controller containing all of the active functions required to implement a full featured open loop, three or four phase motor control system.
This project is very simple car amplifier DC/DC (SMPS) with SG3525 and BUZ11 or you can use any kind of MOSFETs. The output voltage is +/- 35 voltage and it’s regulated and can handle more than 5 Amps.This car amplifier Switch Mode Powder Supply is using a car battery supply from 13V up to 14Volts.
The bq24650 is a highly integrated switch-mode battery charge controller. It provides input voltage regulation, which reduces charge current when input voltage falls below a programmed level. When the input is powered by a solar panel, the input regulation loop lowers the charge current so that the solar panel can provide maximum power output.
