Abstract
A modular arrangement of DC to DC Power conversion units which permits variation of power handling capability without changing the power control system. The conversion units of the stagger-mode type including two pulse width modulated converter sub-units are separated into two individually powered and controlled units. First units of all converters are connected in one series string across a power source and similarly the second units of all converters are connected in a second series string across the power source. Each unit has a capacitor connected across its power input terminals so that the source voltage is evenly divided between converters. With this configuration only one converter need have its current monitored in order to balance the current between the two strings of converter units. The system includes current and voltage protection features appropriate to a high current and high voltage environment.
