PURPOSE: An inverter type power supply is provided to supply power stably to an operation power of an electric or electronic device, to make a transformer core as a radiant panel of a switching element, and to reduce production cost by using a switching element of low price. CONSTITUTION: An inverter type power supply includes; a high voltage transformer T3 for outputting high voltage of predetermined level to supply operation power to an electronic or electric device generator; a rectifying section (REC) for rectifying AC input voltage (AC 110/220V) to DC voltage of a predetermined level; a pair of switching sections (T1,2, Q1,2, R13-16) for switching the voltage supplied from the rectifying section (REC) to frequency of a predetermined level; a pair of transistor (TR1,2) for transmitting a switching signal to a pair of switching sections; and a pulse width modulator (PWM, R1-11, C1,2,6) for outputting the switching signal necessary for switching operation. |
