Perhaps the most important capacitor choice a power supply design engineer can make is the selection of the component for the voltage regulator''s L-C output filter. The job of this circuit is to filter the voltage square wave at its input (the switching node) to produce a constant regulated voltage at its output (V OUT ).
Fortunately, this capacitor discharge calculator makes this step a lot easier. You will need to know the capacitance, initial charge voltage placed on the capacitor, safety threshold voltage (voltage at which the capacitor is
Capacitors play key roles in the design of filters, amplifiers, power supplies and many additional circuits. Here''s a brief guide to the different types and the applications they''re best suited for.
A few examples are to allow only AC current and block DC current, or to smooth a power supply output. A capacitor is able to store energy in an electrostatic field that is generated by a potential difference across the conductors. So when a conductor is subject to a voltage, one plate of the capacitor will collect positive charge while the

Hi Kevin, welcome to the forum. The lead from the cap/amps should be fused at the battery. You can remove the fuse and drain the cap with a test light or spare signal lamp.
There are many different topologies used in power converters, motor drivers and lamp ballasts. Figure 1 shows four basic power switching circuits. Within all of these four fundamental circuits, and in most power switching circuits, the same switch-diode-inductor network is shown within the blue lines.

What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field. This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
Traditionally the ECU is reset by disconnecting the car battery. But there are a few methods to reset your car''s computer without disconnecting power: Key Cycling Method: 1. Turn the key to the ON position without starting
Disconnect the capacitor from its power source. If the capacitor isn’t already removed from whatever you’re working on, ensure you’ve disconnected any power source leading to it. This usually means unplugging the electronic device from the wall outlet or disconnecting the battery in your car.
Capacitor bank can hold dangerous voltage after disconnecting from power system unless discharging devices are connected to the capacitor terminals.
When capacitor is disconnected from power source, an auxiliary relay connects capacitor terminals to resistor ‘r’ dissipating the charge across the resistor. See figure 3. Resistor ‘R’ is the built-in discharge resistance of the capacitors which is typically of high ohmic value.
Capacitors can be rapidly discharged if reactors are connected across the terminals. Under normal power system frequency (50/60 Hz), reactor offers high impedance and hence minimal power loss. When capacitor is disconnected, stored DC voltage is applied across reactor. Ideal reactor offers zero impedance to DC voltage.
If capacitor is disconnected at the zero crossing of AC waveform, no voltage is stored and if capacitor is disconnected at the peak of AC wave, maximum voltage is stored. For discharge resistor sizing, we assume the worst case (capacitor disconnected at AC voltage peak).
Capacitors are found in a number of electrical appliances and pieces of electronic equipment. They store excess electrical energy during power surges and discharge it during power lulls to provide the appliance with a constant, even supply of electricity. Before working on an appliance or electronic device, you must first discharge its capacitor.
