Description
Technical field
The present invention relates to field of switch power, and Pressure and Control circuit is inputted more particularly to one kind.
Background technology
When the input voltage of Switching Power Supply is the high pressure of several hectovolts, then master power switch pipe necessarily high pressure
MOSFET, the usual conducting resistance of high-voltage MOSFET is big, loss caused by identical electric current is flowed through on the big resistance of resistance greatly, so
It is big to have led to the open circuit loss of Switching Power Supply, band carry efficiency it is low, while high voltage input, it is necessary to input filter device it is specified
Voltage is high, and volume is big, and this is contradiction with the highdensity developing direction of Switching Power Supply small size.
In order to solve above-mentioned contradiction, present way is typically that the module input inputted with two low-voltages is connected, defeated
Go out end application in parallel, two module input series connection can be with partial pressure, then the input voltage in each module is exactly original 1/2, defeated
Going out parallel connection can shunt, and can reduce the power output of each module, thus it is unnecessary to the Switching Power Supply of designing high-power
Module expends substantial amounts of R＆D costs.
It is the stable work of switching power converters that pressure is inputted for the switch power module of input series and output parallel
The guarantee of work.If input can not be pressed, output voltage is identical, then the power that a module is born is big, is born in a module
Power it is small, damage can be quickly invalidated by bearing high-power module, then another module also because bear deficiency input high pressure
Also fail.Thus the power module for input series and output parallel has to solve the problems, such as to input voltage un-balance.
In order to solve the problems, such as above-mentioned input voltage un-balance, the invention provides a kind of simple in construction, the input easily realized is pressed
Control circuit.
