Royer Topology Achieves 100μVp-p Noise at 250V Output

Dec 3rd 1997
This circuit's resonant Royer topology achieves 100μVP-P noise at 250V output by minimizing high frequency harmonic in the power drive stage. The self oscillating resonant Royer circuitry is composed of Q2, Q3, C1, T1 and L1. Current flow through L1 causes the T1, Q2, Q3, C1 circuitry to oscillate in resonant fashion, supplying ...
