Abstract
A power supply apparatus having an AC power supply, a transformer, a switching element and a control circuit for controlling an operation of the switching element: where an electrical current is supplied to the primary side of the transformer intermittently when a main unit of an electrical appliance to which the power supply apparatus is applied is in a standby mode so that unnecessary power consumption is reduced. Further, a capacitance is provided between the AC power supply and the control circuit instead of the conventional initializing resistance and the control circuit is driven using an electrical current going through a reactance component of the capacitor, so that the energy loss is not caused any more by the initializing resistance.
Claims28
A power supply apparatus comprising an AC power supply, a transformer, a switching element for relaying an electrical current supplied into said transformer, and a control circuit for controlling an operation of said switching means, wherein said control circuit is provided at a primary side of the transformer and said control circuit controls an operation of said switching element so that the electrical current is supplied into a primary coil of said transformer intermittently.
A power supply apparatus comprising an AC power supply, a transformer, a switching means for switching an electrical current supply line for supplying electrical current to said transformer, a control circuit for controlling an operation of said switching means, wherein said control circuit is provided at a primary side of the transformer and said control circuit controls an operation of said switching means so that the electrical current is supplied into a primary coil of said transformer intermittently.
A power supply apparatus comprising an AC power supply and a transformer, wherein an input voltage is supplied to a primary side of said transformer in a divided condition.
A power supply apparatus comprising an AC power supply, an active filter or an inverter, a control circuit for controlling an operation of said active filter or an inverter and a power supply for driving said control circuit, wherein a capacitor is provided between said AC power supply and said power supply for driving said control circuit so that said power supply for driving said control circuit is operated by using an electrical current going through a reactance component of said capacitor.
