STEVAL-ILH004V1演示板实现了一个数字镇流器在普通照明应用中使用的70瓦HID灯（钠灯或金属卤化物）。镇流器是由升压转换器（功率因数控制器PFC）在过渡模式下工作，并以半桥式驱动在低频方波灯构成的逆变器。The STEVAL-ILH004V1 demonstration board implements a digital ballast for a 70 W HID lamp (sodium or metal halide) used in general lighting applications. The ballast is composed of a boost converter (power factor controller PFC) working in transition mode and an inverter composed of a half-bridge that drive the lamp in low-frequency square wave.Both the half-bridge and the PFC stage are managed by the ST7LITE49K2 that controls the L6382D5, activating all the power switches.
