A method and apparatus is disclosed in which a transformer (22) which has at least one DC output and one input, and a precision timer (38) which generates a control signal having a frequency within a predetermined range of an integer multiple of the carrier frequency spacing. A switch (36) which is connected to the transformer (22) controls the input of the transformer (22). A controller (34) which is electrically connected to said DC output, said precision timer (38) and the switch (36) pulse width modulates said switch (36) at an integer multiple of the carrier frequency spacing whereby the DC output of the transformer (22) is regulated. <IMAGE> |
