A frequency compensation circuit influences an X-radiation protection (XRP) circuit in a high voltage regulator circuit for a cathode ray tube (CRT) to operate properly under varying frequencies of voltage energizing a high voltage transformer. The frequency compensation circuit includes an input to a source of first voltage related to a high voltage output of the high voltage regulator circuit, a voltage source generator responsive to a high voltage generator frequency of the CRT. A voltage controlled circuit is responsive to the voltage source generator for controlling conveyance of the first voltage to the XRP circuit so that a relatively constant proportion of the high voltage output is reported to the XRP circuit under varying high voltage generator frequencies. <IMAGE> |
