ABSTRACT:
A power supply circuit for strobo unit includes a DC-DC converter which steps up a low voltage from a d.c. source to a higher voltage. The converter comprises an oscillation transformer, a PNP transistor and an NPN transistor, both of which are used to form an oscillation circuit. The circuit arrangement provides a stabilized oscillation and eliminates the likelihood of producing an electric shock.
