电流反馈半桥镇流器电路的晶体管的基极驱动 FACT SHEET 046 An electronic ballast: base drive optimisation Introduction Base drive optimisation This Factsheet investigates the transistor base drive The transformer’s auxiliary windings which provide base circuit in a current fed half bridge ballast. Figure 1 drive might contain just one or two turns each. In order shows the simplified circuit. The effect on switching to provide rapid transistor turn-off, their peak loaded waveforms of progressing from a simple base drive output voltage would need to be such that the transistor circuit to the optimised solution will be shown. ’sees’ a turn-off voltage of aro……
