ABSTRACT:
A multiphase high voltage, high power, solid state generator having a pair of 180.degree. out of phase periodic voltage waveforms, undistorted by variation in nonlinear loading, primarily for use as a sustaining voltage source for conductor arrays on a gas discharge display panel. The output of a low voltage oscillator is fed to a phase splitter driver circuit which incorporates complementary emitter follower transistors to provide push-pull output power for each phase split voltage. At least a pair of back-to-back complementary power amplifiers having a common ground or reference point are driven by the 180.degree. out of phase voltages, respectively, of the phase splitter driver circuit. Distortion due to nonlinear loading is reduced by several feedback loops in each complementary amplifier of the back to back pair. Consult the specification for further details and features.
