摘要： An electronic ballast with frequency detection includes a half bridge (124) operably connected to an output of the electronic ballast and responsive to a driving frequency signal, and a microprocessor (128) responsive to the driving frequency signal. The microprocessor (128) controls the electronic ballast in response to the driving frequency signal. The microprocessor (128) can determine if the driving frequency signal is within a desired frequency range and terminate startup if the driving frequency signal is not within the desired frequency range. The electronic ballast can further comprise a regulating pulse width modulator (130) and a frequency adjustment circuit (290). The regulating pulse width modulator (130) is responsive to an effective frequency signal and operably sets the frequency of the driving frequency signal. The frequency adjustment circuit (290) is responsive to a desired frequency signal, which is generated by the microprocessor U2, and generates the effective frequency signal.
