Fault phenomenon: when the equipment is running, the DC voltage and intermediate frequency voltage have reached the rated value, but the DC current is small and the power is low.
Fault analysis and treatment: the fault phenomenon is caused by high load impedance.
(1). Insufficient compensation of load compensation capacitor - add compensation capacitor.
(2). The node contact resistance of the connecting conductor of the slot circuit (LC oscillation circuit) is too large - due to long-term use, the connection of the copper bar of the slot circuit is affected by dust, which increases the contact resistance and increases the impedance of the load.
