Claims

[Scope of utility model registration request]

The drive signal of the transformer output from the oscillator is transmitted to the bridge circuit in which the transistors Tr1 and Tr2 and the transistors Tr3 and Tr4 with different polarities are bridge-connected.
2. In a transformer drive circuit that drives a transformer by inputting to the base terminals of Tr3 and Tr4, the transistors Tr1, Tr2, and Tr4
3. A transformer drive circuit characterized in that a time difference circuit is connected between the base terminal of Tr4 and the oscillator to input drive signals with a time difference.
