After the rectifier the output voltage would change to be DC voltage, but the voltage waveform fluctuate largely. In order to get the smoothing DC voltage waveform, it needs to use the filter method. The filter method is always using the performance of the reactance feature from the reactance components to the AC signals. And it would connect the capacitance or inductance to the load resistance to make up the filter circuit.The picture shows the single-phase half-wave rectifier capacitance filter circuit and working waveform. From the picture (a), when the circuit is not connectted to the capacitance C, the output voltage would be shown in dotted line of picture (b).
