Article Preview

The constant voltage power supply with dual directional reversible PWM compensation has merits of high precision, high efficiency, small volume, and so on. To ensure the quality of supply, it is important to fix the value of inductance, capacitance in main circuit. From the angle of filtering, and through analysis of the circuit working, detailed formulas of the inductance and capacitance calculation are given and an example of it is given too. In parameters calculation, to reduce the volume, the filter inductance is taken a smaller value but the capacitance is taken a greater value; the DC smoothing capacitance should be chosen according to the amplitude limit of DC voltage rising in inversion, and should be taken as great as possible to maintain voltage stabilizing precision.
