A differential charging circuit comprising an active switch device controlled by a differential trigger circuit and a current impedance device to charge a storage battery through an intermediate storage capacitor. A capacitor and commutating inductance are also connected in series with the output to reduce ripple. The differential active switch device is controlled based on a reference potential developed across the current impedance device, and this enables frequency-controlled charging of the storage battery through the commutating type inductance.
