有效的安全电路的电子镇流器

The self−oscillating circuit, commonly used in the low cost half−bridge converter, is prone to thermal runaway when the fluorescent lamp does not strike. As a consequence, either the switches are oversized to sustain such a fault condition, or the circuit includes a safety
network to avoid this risk. Although several schematics are usable to perform such a function, the one described in this paper is easy to implement and does not influence the normal operation of the converter.， 大小：671 KB
