High Voltage Power Supply scheme

The schematic diagram is derived from the circuit of a High Voltage Power Supply utilizing the PWM IC TL494. This power supply requires a suitable alternating voltage source of 12 V / 800 mA. An alternating voltage is rectified using a diode bridge rated for a maximum current of 1 A. The converter's output voltage is adjustable. This DC to DC Converter schematic illustrates the conversion of a 5-volt input voltage to an output voltage of up to 30V. Direct current is transformed into an alternating signal using a hysteresis inverter built with a Schmitt trigger and resonant characteristics. Experimental studies on a highly stable voltage source schematic indicate that within a temperature range of -18 °C to 50 °C, the temperature error remains minimal. A simple inverter circuit capable of generating voltages from 1.5V to 3V can be constructed using a slightly modified multivibrator design, operating at an approximate frequency of 130 kHz. The circuit also includes a precision high voltage regulator diagram based on the 3-terminal adjustable regulator LM317L IC, which requires an input voltage of at least 178V and can provide an output voltage ranging from 8V to 160V at a current of 25 mA.

The High Voltage Power Supply schematic utilizing the TL494 PWM IC is designed for applications requiring stable high voltage outputs. The input section features a 12V AC source, which is rectified by a diode bridge to convert the AC voltage into DC. The diode bridge must be selected to handle a peak current of at least 1 A to ensure reliable operation. Following rectification, the output voltage can be adjusted through feedback mechanisms integrated into the TL494 control loop, allowing for fine-tuning of the output voltage to meet specific load requirements.

For the DC to DC converter section, the circuit effectively steps up the initial 5V input to a maximum of 30V. This conversion is achieved using a switching mechanism that rapidly toggles the input voltage, generating an alternating waveform that is then transformed into a higher voltage level. The hysteresis inverter, employing a Schmitt trigger, ensures stable oscillation and minimizes the risk of oscillation failure due to noise or minor voltage fluctuations.

The experimental results from the highly stable voltage source schematic demonstrate its robustness across various temperatures, highlighting its suitability for applications in environments with significant temperature variations. The design's ability to maintain a low temperature error is critical for precision applications where voltage stability is paramount.

The inverter circuit capable of generating voltages from 1.5V to 3V is particularly useful for low-power applications. By modifying a standard multivibrator circuit, the design achieves a frequency of approximately 130 kHz, facilitating efficient operation in small-scale electronic devices.

Finally, the precision high voltage regulator circuit based on the LM317L IC is designed for applications requiring a regulated output voltage. The circuit requires a minimum input voltage of 178V to function correctly and can deliver a regulated output voltage from 8V to 160V, making it versatile for various high voltage applications while maintaining a current output of 25 mA.
