The actual peak current will be less due to capacitor and switch ESR, but it looks like you''ll be in the right ballpark IF the coil does not self-destruct from heating and inter-turn magnetic forces. You''ll also need some way to protect your polarized capacitor bank from reverse current (such as a heavy rectifier across the capacitor bank).

6 Frequently Asked Questions about “How to discharge the inverter capacitor bank”

How do you discharge a capacitor?

A fast way to discharge capacitor is to connect switchable low ohmic value resistor across 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.

Can you discharge a capacitor with a screwdriver?

It's often safe to discharge a capacitor using a common insulated screwdriver; however, it is usually a good idea to put together a capacitor discharge tool and use that for electronics with larger capacitors such as household appliances. Start by checking for a charge in your capacitor, then choose a method to discharge it if needed.

Can a power capacitor be discharged?

For most power system switching applications, once the voltage is decayed below 10% it is typically safe for reclosing, switching etc. The most common method of power capacitor discharge is to permanently connect resistors across the terminals.

How do you use a capacitor discharge resistor?

Select an appropriate discharge resistor based on capacitor voltage and capacitance. Connect the discharge resistor across the capacitor terminals using insulated probes. Monitor voltage decay using a high-impedance voltmeter in parallel with the resistor. Maintain the connection until voltage drops below 50V or to the specified safe level.

What voltage should a capacitor be discharged?

Different discharge methods are chosen based on the measured voltage of the capacitor: Less than 10 volts: This voltage is generally considered safe and does not require additional discharge procedures. Between 10 and 99 volts: Although low, this voltage still poses some risk. Use simple tools like a screwdriver for quick discharge in this case.

Can capacitor bank hold dangerous voltage after disconnecting from power system?

Capacitor bank can hold dangerous voltage after disconnecting from power system unless discharging devices are connected to the capacitor terminals.
