发明名称 Electronic ballast circuit for operating a high intensity discharge lamp
摘要 An electronic ballast circuit (FIG. 1) includes a voltage-regulated DC power source and an H-bridge having a plurality of transistors (Q5, Q6, Q7, Q8). The circuit operates a high intensity discharge lamp (50). A regulating circuit electrically connected to the transistors regulates the peak current flowing through the H-bridge by discharging a parasitic capacitance (C parasitic).
