ABSTRACT:
A buffer circuit, which supplies current to a capacitive load, has a first circuit for reducing the power supply charging current to the capacitive load during switching intervals. The first circuit includes a charge storage device precharged between inverter switching intervals to produce at least a portion of the load charging current during the switching intervals. A second circuit includes a switching element connected between the power supply and the capacitive load to electrically connect the power supply through the second circuit to the load at a selected time in the switching interval to supplement the charging current produced by the charge storage device.
