| Summary: | Configurations provide reduction in the hum and the weak shocks that are produced in audio equipments where electrical power is supplied. Switching electrical power sources include, a rectification element that rectifies a current that is supplied, a switching element that switches the input voltage that has been rectified by the rectification element, an oscillator circuit that oscillates at a specified frequency and drives the switching element by means of oscillation, and a transformer with which the voltage that has been switched by the switching element is input to the primary oil and wherein an electrical power source output is obtained from a secondary coil. A plurality of capacitors are connected to the conductors. |
