Electronic ballast circuits used to control fluorescent lamps include a series L, parallel R-C, resonant tank output circuit driven by a half-bridge switching circuit (). This resonant topology allows ...

TDK’s EPCOS B3264xH series of film capacitors meets the demands of high-frequency applications in advanced power electronics ...

Ballast design assistant (BDA) Software A software program (BDA V4.0) has been developed for easy design and prototyping of electronic ballasts. This program includes a graphical interface with a ...

The electronic ballast circuit must perform the following basic functions. First, they must provide a high enough strike voltage across the lamp's electrodes.

HID BALLAST CIRCUIT TOPOLOGY The ballast circuitry for an HID lamp (Fig. 2) is complex. The boost power-factor correction (PFC) stage runs in critical-conduction mode.

So electronic ballasts generally incorporate power-factor-correction (PFC) circuits to compensate. PFC chips basically keep the switch on time at a fixed relationship to the input line voltage so ...

Electronic ballasts help in to stable the overall current flow. With -ve supply of current flow, the electronic ballasts gainvoltage power from a high voltage supply and spread the voltage power at ...

The case is Lighting Ballast Control v Phillips Electronic North America. The chasm between the judges is the latest in a series of disagreements over what is eligible for patent protection. In May, ...

Before the days of electronic loads, equipment grounding conductors (EGCs) were not required at the branch circuit level. But with the advent of electronic-based ballasts for fluorescent and HID ...
