High collector-current spikes , always present in conventional dc-to-dc converters that use a single saturable transformer, damage switching transistors, generate electromagnetic interference and keep the convention efficiency at a low 80%. Reducing the spikes with the usual bruteforce methode-by addition of a capacitor or a diode across the switching transistors-results in a decreases in efficiency. But tile spikes can be eliminated if a second transformer is added to the dc-to-dc converter
