    rectifier Function
    
    Returns the capacitance (in Farads) for a needed capacitor in
    a rectifier configuration given the system frequency (in Hz),
    the load (in amps) and the desired voltage ripple.
    
    Parameters
    ----------
    Iload:      float
                The load current that must be met.
    fswitch:    float
                The switching frequency of the system.
    dVout:      float
                Desired delta-V on the output.
    
    Returns
    -------
    C:          float
                Required capacitance (in Farads) to meet arguments.
