What is an Inductive Ballast?Inductive Ballast definitionInductive Ballast is an iron core inductance coil, the nature of inductance is that when the current in the coil changes, it will cause a change in magnetic flux in the coil, resulting in induced electromotive force, and its direction is opposite to the direction of the current change, thus hindering the current change.Working principle of Inductive BallastWhen the 220V 50Hz AC power supply is applied in the switch closing circuit, the cur

What is an Electronic Ballast?Electronic Ballast DefinitionElectronic Ballast is a kind of Ballast, refers to the use of electronic technology to drive the electric light source, so that it produces the required lighting electronic equipment.Working principle of Electronic BallastThe power supply is converted into a DC power supply after passing through a radio frequency interference (RFI) filter, full wave rectification, and a passive (or active) power factor corrector (PPFC or APFC). Through t

What is a Ballast Resistor?Ballast definitionA ballast resistor is a resistor used to limit the current in a circuit and prevent overcurrent faults.Ballast role To maintain the stability of the circuit Compensate for changes and protect other components of the networkClassification of ballasts Inductive ballast Electronic ballastBallast application Used in the ignition system of automobiles Lighting system

What is a Ballast Resistor?A ballast resistor is defined as a resistor inserted into a circuit to minimize current. Ballast resistors also help to avoid over-current faults in a circuit. An “electric ballast” is a more general term used to refer to an electrical device used to maintain a circuit’s stability by limiting the value of current and voltage. Electric ballasts can be resistors, capacitors, inductors, or a combination of these.Ballast resistors are able to change resistance with the cur
