Common power circuit has AC power circuit, DC power supply circuit etc..Circuit claims electronic loop, is by electric
Equipment and components and parts, are coupled together by certain way, for the totality that electric charge circulation provides path, are also electronic circuit or are claimed electricity
Air circuit, abbreviation network or loop.Such as power supply, resistance, electric capacity, inductance, diode, audion, transistor, IC and telegraph key,
The network of composition, hardware.Negative charge can flow wherein.The size of circuit, can differ greatly, little integrated on silicon chip
Circuit, greatly to high-low pressure power transmission network.There is integrated circuit, also there is separating element circuit.They coexist, each have their own speciality.
DC power supply circuit is divided into two kinds of forms of Switching Power Supply and unswitched power, and circuit also differs widely.Switching Power Supply
Typically transformator is not used;Unswitched power is traditional design, many in power circuit to be come after transformation again using transformator
The mode of rectifying and wave-filtering.Several components are interconnected by wire, are formed " circuit ", it is also possible to referred to as " network ".More specifically,
Circuit can be the network to form closed-loop path." branch road " is a part for circuit, and each component has the branch road that it solely belongs to.
The joining of any two or more pieces branch road, referred to as " node ".
Power circuit generally can be divided into switching power circuit, voltage-stabilized power supply circuit, stabilized current supply circuit, power power-supply electricity
Road, inverter power circuit, DC-DC power source circuit, protection power circuit etc..
At present existing circuit power installs inconvenient, and filter effect is general, and structural stability is poor, adjusts inconvenient.
