Abstract
A structure and method of operating an optical step-up transformer are described. The optical step-up transformer has at least one photodiode and at least one photoreceiver. The photoreceiver receives light emitted from the photodiode and generates a voltage proportional to the number of series-connected photoreceivers. The photodiode and photoreceiver may be electrically isolated or may share a common anode or cathode. The voltage applied to the photodiode may be a DC or PWM signal.
