Abstract:
A charge pump electronic ballast for use with low input voltage is described. The charge pump electronic ballast includes a DC/AC inverter circuit having two switching transistors, a resonant circuit having an inductor and a capacitor. The charge pump electronic ballast further includes a voltage multiplying rectifying circuit for transforming low input AC voltage into high output DC voltage, and a charge pump circuit having an inductor and a first pump capacitor.
