Abstract
A high voltage power supply circuit for a high frequency medical X-ray generator comprises a high voltage transformer having a primary and a secondary and an inverter circuit responsive to predetermined control input signals for producing corresponding inverter output signals. A responant circuit is coupled with the inverter circuit and is resonsive to the inverter output signals for producing corresponding voltage pulses for energizing the primary of the high voltage transformer. The resonant circuit includes a capacitive component and an inductive component, the latter being provided by the primary of the high voltage transformer coupled in series circuit with the inverter circuit and with the capacitive component. A KVP regulator circuit provides the control input signals for the inverter circuit in the form of a series of KV firing pulses.
