[2] Operation descriptions
1. Normal control
1) Application outline
As shown in figure 1, the standard application of the AN8031 is a booster chopper circuit, which inputs
the voltage rectified from the commercial supply of 100 V/200 V (A in figure 1) and outputs the DC voltage
of 400 V (B in figure 1).
It controls so that the input current proportional to the input voltage (C, D in figure 1) could be flown.
The reason for selecting the output voltage of 400 V is that the withstanding voltage of components and
the operation limitation of booster chopper (input voltage
<
output voltage) under the worldwide input
voltage are taken into consideration.
