A hydrogen fuel cell bus has three main components: the fuel cell stack, the electric motor, and the hydrogen storage tanks. The fuel cell stack is made up of individual fuel cells that combine hydrogen and oxygen to produce electricity, heat, and water as byproducts. The electric motor is...
The basic principle behind the working of oscillators can be understood by analyzing the behavior of an LC tank circuit shown in Figure 1 below, which employs aninductorL and a completely pre-chargedcapacitorC as its components. Here, at first, the capacitor starts to discharge via the inductor...
Real inductors have turn-to-turn winding capacitance that acts as if it were a parallel circuit element. The self-resonant frequency (SRF) of an inductor is the frequency at which the inductive reactance is equal in magnitude to the capacitive reactance of the windings. At the SRF, the induc...
If we filled the first tank with water and let the water flow into the second tank, would it fill the tank completely? Of course it would, because the volume of the first tank is 6 (W) from 12 (V) x 0.5 (A) and the second tank is 3 (W) from 3.7 (V) x 0.8 (A). Normall...
SCADA is a system used to monitor and analyze data, and control industrial processes. Securing SCADA systems is crucial and vital to the safe operations of industrial machines. Discover how SCADA works, the risks of SCADA systems, and how Fortinet secure
The water pressure at the end of the hose is equivalent to the voltage or potential difference in an electric circuit. The water in the tank is equivalent to the electric charge. Now if we increase the amount of water in the tank then more pressure is developed at the end of the hose....
The same is true of an electrical system: Increasing the voltage will make more current flow. Let's say you increase the diameter of the hose and all of the fittings to the tank. You probably guessed that this also makes more water come out of the hose. This is like decreasing the ...
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
100% is a full tank, 50% is half full. As you close in on O% you’re running on empty — then you’re out of gas. Depth of Discharge (DoD) measures a battery’s state of charge in reverse. The formula is DoD = 1 – SoC. In other words, if you only have 10% of the ...
When outsourcing Big Switch PCBs, partnering with the right manufacturer is key for ensuring optimal quality, performance and reliability. Some of the top criteria in selecting a supplier include: 1. Technical Capability:Possession of latest PCB technologies and high layer count capability with suitable...
