6 FAQs about [Bulk Capacitor Performance]
How do bulk capacitors work?
Bulk capacitors control the voltage deviation at the input when the converter is responding to an output load transient. The higher the capacitance, the lower the deviation. Therefore, the size of the input bulk capacitor is determined by the size of the output current transient and the allowable input voltage deviation.
What is the main purpose of bulk input capacitors?
What is the main purpose of bulk input capacitors in a power supply design? The main purpose of bulk capacitors on the input of a design is to control input spikes when there is an output current transient. It is important to keep in mind that when there is an output load transient this energy must come from the input of the regulator.
What determines the size of a bulk capacitor?
The higher the capacitance, the lower the deviation. Therefore, the size of the input bulk capacitor is determined by the size of the output current transient and the allowable input voltage deviation. The amplitude of the input voltage deviation during a transient is directly proportional to the load current change.
Why are electrolytic capacitors used for bulk capacitance?
The necessary capacitance needed can often be quite large and therefore Electrolytic Capacitors are often used for bulk capacitance. The main purpose of bulk capacitors on the input of a design is to control input spikes when there is an output current transient.
How does a bulk capacitor control a load transient?
It is important to keep in mind that when there is an output load transient this energy must come from the input of the regulator. Bulk capacitors can control the voltage ripple at the input when the converter is responding to a load transient.
What is the difference between a bulk capacitor and a linear supply?
The difference is one of scale, both of current and of time. A bulk capacitor is used to prevent the output of a supply from dropping too far during the periods when current is not available. For line-powered linear supplies, this would occur during the periods (say, 10s of msec) that the line voltage is near zero.
