Abstract

A capacitive power supply having a charge equalization cir-cuit. The charge equalization circuit is comprised of a shunt circuit (184) connected in a parallel connection with capacitive elements (170) of the capacitive power supply. Once a charging current is ap-plied to the capacitive power supply to store charge thereupon to form thereby a potential difference across the capacitive elements (170) of a predetermined level, the shunt circuit (184) forms a shunt to shunt the charging current thereto.
