High-pressure sodium ballasts, which consists of high-power active filter integrated circuits, high-power MOS transistor, diodes, capacitors, resistors and transformer T1 is composed of a high-power active filter circuit to the switching circuit provides operating power to adjust the powerfactor and a stable output power, in the switching circuit is further provided a dedicated overcurrent protection circuit. The electronic ballasts features are: high efficiency, the effectiveness factor greater than 0.99, the energy-saving effect is remarkable, less than 10% of the total content of the third harmonic, can use a large area, low temperature rise, practical and reliable.
