Description of the invention: [Technical field to which the invention pertains] The present invention relates to the _ species in the province of two, especially the use of 雔; ^ dry: nuclear type I... type wide adjustment, ^ spear The modulating device is made of an integrated electric enthalpy of a polar transistor structure. In the 'pulse width used to control the switching of the power switch 【Prior Art】 According to the known DC power supply device, such as the exchange ^ Φ r λγ ^ '屯源 supply ^Crystal CSwitchingPowerSupply), in order to reduce the change ^ The limbs are private, and most of them use the high-frequency pulse width modulation (the circuit of i does not think), the transformer T1 divides the circuit into the -stage circuit 101 and the secondary-side circuit 102, which is the second time The j-side 102 is electrically connected to the secondary side 101 and the secondary side 102 by a photonic crystal ηι and a photodiode, but the optical signal can be used to feedback the voltage or current of the secondary side 1〇2. Output change signal to the primary side = synchronously adjust the voltage and current of the primary side 101 and the secondary side 1〇2 or as a feedback signal for overcurrent and short circuit protection. The primary side 1〇1 inputs an alternating voltage, and the alternating current voltage VAC passes through a filter 1010, a bridge type is generally BD1, and a south voltage filter 'wave capacitor C1 becomes a direct current voltage vin. The direct current voltage Vin is one by one. The pulse wave adjustment control unit 讥 controls the power transistor switch Q1 The pass cycle is further transmitted to the primary winding of the transformer T1. At the same time, the secondary winding of the transformer T1 senses the output voltage, and the output voltage is rectified and filtered by the diode D1 and the electrolytic capacitor C2 to generate a stable DC voltage Vout output. The DC voltage Vout is converted into a voltage signal VFB and fed back to the pulse width adjustment control unit m of the primary side 101 through a feedback regulator D3 and an optocoupler u. At the same time, the power transistor is used. When the switch Q1 is turned on, a current feedback signal Vcs is obtained through the resistor ,, and the current return signal Vcs is transmitted to the pulse width adjustment control unit 讥, and the pulse wave miscellaneous control solution π obtains the current feedback call Ves and The voltage signal VFB is used to calculate the output of an adjustment pulse; the skin pfM is connected to the power transistor switch Q1, and the output DC voltage V〇ut is stabilized. The assimilation is based on the conscious awareness of the gradual head-up, and has a power-saving mode ((5) (5) Mode) design power supply The supply of wire has become more and more popular, and each pulse wave adjustment controller (PffM IC) is designed to be launched in a power-saving mode (G-de).
