13KV High voltage power supply

Description: This high-voltage power supply features an inverter circuit centered around Q1, which generates 150-V pulses for the converter SCR1 and capacitor C2. The output from component ?2 produces a 4.5-kV pulse, which is further amplified by a voltage-tripler network to achieve an output voltage of 13.5 kV. Additionally, R1 functions as a 3k to 500K current transformer (CT) for an audio transformer, while L2 serves as a flash tube trigger transformer with a secondary voltage rating of 6 kV.

The high-voltage power supply circuit is designed to convert low voltage input into high-voltage output through a series of components that work in conjunction. The inverter circuit, utilizing Q1, operates by switching the input voltage to create a pulsed output. This pulsed output is essential for driving the silicon-controlled rectifier (SCR1), which acts as a controlled switch that can handle high voltages and currents.

Capacitor C2 is employed to smooth the output voltage and provide energy storage, ensuring that the SCR operates efficiently during the switching process. The component labeled ?2 is critical as it steps up the voltage to 4.5 kV, which is then processed by the voltage-tripler network. This network typically consists of capacitors and diodes arranged to multiply the voltage, ultimately delivering a high output of 13.5 kV.

The inclusion of R1 as a current transformer allows for the integration of audio signals within the circuit, facilitating the control and modulation of the high-voltage output. The range of 3k to 500K indicates its versatility in handling different audio frequencies and signal levels.

L2, the flash tube trigger transformer, is specifically designed to generate a high-voltage pulse necessary for triggering flash tubes, which are commonly used in photography and other applications requiring intense bursts of light. With a secondary voltage of 6 kV, L2 ensures that the triggering mechanism operates effectively, providing the necessary energy to initiate the flash.
