Help me understand this CDI circuit
Without primary L, Coupling factor and n turns ratio, it is hard to synthesize, but I’Lyl take a stab at it.
The diodes clamp the negative spikes and the positive pulses trigger the Triac to discharge the stored Cap voltage into a step up transformer.
The cap voltage ought to look like a sawtooth signal.
The input secondary may not look so symmetrical with a negative diode clamp load. The output ought to reach 40kV into spark plug carbon resistance wire.
