I ran a quick simulation... X1 is a Darlington transistor used as follower, so its Vce will be 2*Vbe plus voltage drop in R1, so about 1.5V. With 400mA through the load it dissipates 0.6W. With the i …

It depends on what you're doing with the motor. If all the MOSFETs in the H-bridge are off, and the motor is turning, then it will act as a generator. The MOSFET body diodes will act as rectifiers, an …

Datasheet says: "Effective Output Capacitance, Energy Related" = 15pF Coss (Cds+Cgd) capacitance is charged from the power supply every time the FET turns off, which stores some energy. When the FET t …

Three problems: 1N4004 is rated to 1A, not 20A. And it is too slow. You can use the FET body diodes instead. They should not conduct often if the FETs are driven synchronously, so there should be no …

If the 24V is really 24V, and not automotive 24V than can get a lot higher, I'd use a pair of cheap half-bridge MOSFET drivers with integrated adaptive dead time like NCP5901, ADP3120, ADP3110, etc. I …

Besides all the issues pointed out by rdtsc, bipolar transistors in a H-bridge with an inductive load absolutely need a free-wheeling diode across each transistor. Otherwise, when they turn off, the k …

Am I using too many components for an Engine like this? No, if you want to change direction you need a H-bridge. Is This 10k Necessary for P Channel? Can't say without reading driver datasheet. I …

The chip has internal MOSFETs with body diodes that will act as rectifiers, so when the motor acts as generator, or produces back-EMF, the energy will be sent into the power supply. Protection measure …

If you apply a lowpass filter to the measured voltage, the result will be averaged, and it will be proportional to duty cycle. If you then use a microcontroller SAR ADC to acquire it, since there will …

boost converter which will boost the 12V to 120V, Transformer will be much more efficient and cheaper than boost converter for that high output/input voltage ratio. Say you need 120V 10A, if it is 1 …

Suppose the load is inductive, like a motor. T2 T3 are ON, and current flows according to the arrows. Now T2 T3 turn off, but current in the inductive load does not drop to zero, it keeps flowing acc …

Capacitor: 40uF, DC Power Source: 100V, DC Switching time: ~us (originally nanoseconds) Current in a capacitor can be calculated from the derivative vs time of voltage across it: \$ i = C dv/dt \$ W …

Notice the fine print on DMP3056 datasheet about how RthJA of 91°C/W is measured... Note 5: Device mounted on FR-4 substrate PC board, 2oz copper, with thermal vias to bottom layer 1inch square coppe …

On your layout the decoupling cap (finger-painted red) is very far away from the chip, there is a 5R resistor in series (purple) and the current loop area (highlighted in yellow) is quite large. Th …

I tried using a Raspberry Pi with 14 x L298N Dual H-Bridge Driver Modules to run the electromagnets and it usually works, but there's a lot of wiring involved with the H-Bridge modules, making faul …
