I came across a straightforward high voltage circuit, and when I combined it with my circuit archive, I became curious about the outcome when using a PC power transformer that provides around 1.2 kilovolts (1.2kV).
Please note the following CAUTION: The circuit generates high voltage, so it should not be operated without taking the necessary safety precautions. Also, 220 volts are not suitable for devices designed to operate with AC power, such as TVs and monitors.
I directly connected a 220-volt, 50-watt lamp to the transformer’s output, and without the use of an FR107 fast diode, I measured the lamp’s DC voltage while it was connected. I employed a half-wave rectifier with the lamp in the circuit, and I conducted the DC voltage measurement without applying a load to the 270-volt fraction.

Simple Scheme of Circuit
The central component of this compact voltage converter, which transforms a 12VDC source into 220VAC, is the CMOS 4047 integrated circuit, discreetly housed within this DIY 12V to 220V DC to AC converter. Within the circuit, the 4047 serves as an astable multivibrator, generating a balanced square wave signal at pins 10 and 11. This signal is then amplified by two Darlington transistors before reaching the secondary coil of the mains transformer, which has a rating of 2x10V/60W.
By adjusting P1, you can alter the output frequency within the range of 50Hz to 400Hz. While it’s not typically found in professional DC to AC converters, this setup can power certain household appliances. It’s crucial to note that the output signal is in a square wave form, not a sine wave. Consequently, it’s unsuitable for powering devices like televisions, laptops, or monitors. Instead, it’s best suited for lighting, power tools, and other lower-cost appliances.
The FR107, known as a Fast Recovery Rectifier diode, is specifically designed for circuits that need to convert alternating current to direct current. It can handle currents of up to 1 A and boasts a peak inverse voltage (PIV) rating of 1,000 V.
In summary, the FR107 is a Fast Recovery Rectifier diode employed for AC to DC conversion in circuits. It possesses a PIV rating of 1,000 V and can carry currents up to 1 A.
