Cycle use is when you charge and use at the same time, like in a car. With fast charge the max voltage is 14.4-15.5V depending on temperature, 15.5V at -20 centigrade.
Standby use is maintain the battery charged with trickle current.
The easy way is to charge with 10-20% of Ah and to change to...
Sometimes inductive load on the drain causes large transients. The internal cap between the drain and the gate causes the gate voltage to rise above 30V, the zener snubber suppose to protect the gate. Some datasheets recommend it and some IR mosfets have integrated zeners.
On switching the gate on the 1uF increases the charge current of the Ciss for a duration of few microseconds, that switches on the mosfet faster. Maybe it decreases switching loss.
When the load is inductive the gate drive is deliberately slowed for the purpose of using the mosfet as snubbing for high frequencies.
To my opinion this gate drive is weak but good enough. I only suspect that there is another error in the drawing and the gates should be connected to the...
One possibility is that high input signal to the opamp causes high current on the power rail of the opamp and that shuts down the 16V supply or adjusts it. It needs looking at the 16V supply schematic.
I guess it's a supply for control circuitry of a generator.
The reflected voltage is 10 to 15V. Since the load on the 24V and the feedback winding is constant the switch on time vary when the high voltage vary.
The caps are small because of the high frequency.
The voltage on the mosfets can be...
Connect one side of your pot to +5v and the other side to grd. The center of the pot goes to the Arduino's input. Write a routine in your code to convert analogeRead of 0 to -5V, 2.5V to 0V and 5V to +5V.
The Vref is a stable voltage. It can vary with temperature and from one chip to another from 2.3 to 2.4. If you cannot get the right resistors add a trimmer in series to Ra. Fully charged batt is 28.4V. This voltage depends on the charge current and the size of the batt. With a trimmer you can...
When counter/timer uses external input you must use synchronization, that limits the input to be half the crystal frequency when the input is 50% duty cycle. To count 20Mhz 50% duty cycle you have to use the pre-scaler and that reduces the resolution.
This website has a few samples, I tried a...
Connect the bases of complementary transistors to the output of LM380 and take the feedback to the inverting input from the emitters, this way the transistors are in the loop and you will get low distortion. A small cap on the feedback will take care of the instability.
Switching amplifier has a 0V offset. You can still measure the offset by shorting the input to ground and divide the output by the gain, the same way as any other amplifier.
The idea of these amplifiers is switching the input from ground to input voltage and subtracting the two outputs with...
You can't get what you want with one converter. There are 2 options; 1. With step up converter convert the input to say 30V and then a step down converter to 12V. 2. Step down converter to 5V and then step up to to 12V.
Option 1 is likely to be more efficient.
