Normal control 1) Application outline As shown in figure 1, the standard application of the AN8032 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. C. Input voltage (VIN) Commercial power supply (AC) Figure 1. Application outline description Input current proportional to input voltage flows. Booster chopper circuit Active filter 0 A D.
