NON-ZVC(ZERO VOLTAGE CROSSING) LOW NOISE HIGH VOLTAGE POWER SUPPLY BY PHASE PILED

摘要

PURPOSE: A phase-interleaved non-ZVC(zero voltage crossing) is provided to basically remove switching noise generated in ZVC state. CONSTITUTION: The current of power supply input terminal(1) is provided to each switching transistor(4) through a primary coil of power trans(2). A bias control terminal(3) automatically controls base of the switching transistor and emitter bias voltage. The collector output wave type of the switching transistor has 180 degree of phase difference. The voltage corresponding to the collector voltage difference of switching transistor is applied to the primary power trans.
