PDV21-3,50-V-M is a high frequency, high voltage, switching power supply for electrical application and is widely used in the fields of transistors, electrical engines, switches, high-voltage switches, television and communications. This device consists of a main circuit and a secondary circuit with a power factor corrector, a high frequency and voltage multiplier circuit, and a supervisory circuit. The main circuit is composed of a power factor corrector, a high-voltage and frequency multiplier circuit, and a stabilization circuit. The power factor corrector provides a stabilized voltage to the high-frequency and voltage multiplier circuit, which is responsible for increasing the output voltage with the help of solid state switching elements. The stabilization circuit provides a low-impedance condition for the output voltage, which ensures its stability. The secondary circuit consists of a protection circuit, which is responsible for preventing the high-voltage capacitors from overloading, and current limiting circuits which prevent the over-current condition before the switching elements from creating damage to the power supply.It works based on multiple voltage steps. The high frequency current is generated in the multiplier and then it is stepped up to the required voltage level. The high voltage is generated by the Zener diodes which converts the DC voltage to a high-voltage AC signal and then this signal is fed to the power factors corrector. This corrector then stabilizes the signal and reduces the harmonic distortion in the output. Finally, the Voltage Multiplier is responsible for amplifying the voltage to the desired level and then it is sent to the output. This power supply has a wide range of applications due to its high-frequency and high-voltage handling capacity. It is used in transistors, electrical engines, switches, high-voltage switches, television and communications devices. It can also be used in circuit protection applications as the protection circuit provides a reliable protection against any overloading or excessive current conditions. In conclusion, PDV21-3,50-V-M is a high-frequency, high-voltage switching power supply that supports a wide range of applications. Its main circuit is composed of a power factor corrector, a high-voltage and frequency multiplier circuit, and a stabilization circuit and the secondary circuit consists of a protection circuit, which is responsible for preventing the high-voltage capacitors from overloading, and current limiting circuits which prevent the over-current condition before the switching elements from creating damage.
