Electronic stabilizer having a variable frequency soft start circuit
 An electronic stabilizer having a variable frequency soft start circuit, said circuit having a secondary coil coupled to a drive transformer of the electronic stabilizer. In the initial period when power is connected, the secondary coil may supply an induced voltage to a capacitor to generate a forward voltage to connect primary transistor to allow an inductance element to parallel the secondary coil to reduce the total inductance. The operating frequency of an LC oscillating circuit of the stabilizer hence increases. Relatively, the energy obtainable by the fluorescent lamp is reduced. The soft start circuit is further provided with a discharge loop of a secondary transistor for discharging of the capacitor to ensure that soft starts may be achieved under any conditions.
