Abstract: The DC/DC power source converter is can transform one kind of DC voltage other one kind or several kind of DC voltage highly effective generator set. First introduced that the DC/DC power source converter analysis situs the classification, then has induced the common DC/DC power source converter’s analysis situs type by the tabular form, including circuit structure, transfer function, voltage and current waveform as well as controller’s typical product and so on.

This article first part is “the DC/DC power source converter analysis situs classification”, the second part is in refers to the American TI Corporation material in the foundation to compose becomes, increased each kind of DC/DC power source converter’s main feature and the PWM controller’s typical product newly, in addition defers to the goal to the circuit structure, the waveform parameter and the juice calculated that in the formula the physical quantity has made the unification. This article characteristic tabular form has induced the common DC/DC power source converter’s topology sufficiently. This to the power source specialized general technical personnel is a rare technical data.
1 DC/DC power source converter topology classification
The DC/DC power source converter’s analysis situs type mainly has the following 13 kinds:
(1)Buck Converter voltage dropping type converter;
(2)Boost Conyerter pressure-rise -like converter;
(3)Buck-Boost Converter voltage dropping/pressure-rise -like converter, including reversal of poles (Inverting) type converter;
(4)Cuk Converter pressure-rise, pressure-rise tandem converter;
(5) SEPIC (Single Endcd Pdimary Inductor Converter) a single end side inductance type converter;
(6)F1yback Converter instead stirs up-like (also calls back feed type) the converter;
(7)Eorward Converter is stirring up-like the converter:
(8)Double Switches Forward the Converter double switch is stirring up-like the converter;
(9)Active Clamp Forward Converter active clamp
(0)Half Bridge Converter semi-bridge system converter;
(11)Full Bridge Converter entire bridge-type converter;
(12)Push-pall Convener push-pull type converter:
(13)Phase Shift Switching ZVT (Phase Shift Switching Zero Voltage Transition) phase shifting type zero potential switch converter.
2 common DC/DC power source converter’s analysis situs type
The common DC/DC power source converter’s analysis situs type sees the Table 1~ tables 3 to arrange in order. In the table gives the different circuit structure, simultaneously also gives the corresponding voltage and the current waveform (supposes related inductance electric current for continuous working way). PWM expressed that the pulse-duration modulation profile, U1 is the cocurrent input voltage, UDS is the power ji turns off the tube S1(MOSFFT) leaks a source voltage. ID1 is the S1 drain electrode electric current. IF1 is the D1 operating current, U0 is the output voltage, IL is the load current. T is the cycle, t is UO assumes the high level (or low level) when asked that D is a dutyfactor, has the relationship: D=t/T. C1, C2 are the input end filter electric capacity, CO are the out-port filter electric capacity, L1, L2 are inductance.
