Inverter high voltage shutdown capacitor

What is lm27761 low-noise regulated switched-capacitor voltage inverter?

The LM27761 low-noise regulated switched-capacitor voltage inverter delivers a very low-noise adjustable output for an input voltage in the range of 2.7 V to 5.5 V. Four low-cost capacitors are used in the application solution to provide up to 250 mA of output current. The regulated output for the device is adjustable between −1.5 V and −5 V.

What power resistor do you use for a car inverter?

Ours is an electric car using a 588 V (maximum) battery to drive the motor. The inverter has a capacitance that, by the competition rules, we need to discharge when we shutdown the car. For this, we use a 4.7 kΩ power resistor.

How does a series parallel capacitor work?

One capacitor is charged to match the input voltage magnitude, while the other two capacitors store twice this magnitude. Through a series-parallel combination with switching operations, all capacitors are effectively charged and discharged within each cycle, ensuring natural voltage balance.

When should a capacitor be discharged?

I''m in charge of designing the discharge circuit, in which I have an input that indicates when I want to discharge the capacitor. When the input is 0 V, the discharging circuit should be closed so when the car turns off (or fails) it should be discharging.
