Voltage converter and regulator

摘要: Voltage converter and regulator circuits are disclosed for converting a relatively low direct current input voltage to higher output use in photographic flash equipment, power supplies energy discharge applications. A battery starting transistor oscillator which provides through drive circuit energize the primary winding of transformer, during ''''on'''' portion cycle. During ''''off'''' cycle, no is supplied transformer winding, secondary charging storage capacitor. While being capacitor, maintained condition by second simultaneously flows used shunt away from oscillator. regulation accomplished neon lamp zener diode serially connected with resistor, across excess discharged capacitor feed-back connection responsive flowing switching The duration cycle can be controlled variable also provided mechanical switch selection between different frequencies.
