As a result, a pulsating waveform of the load current is obtained.ĭuring the input supply half cycle, the thyristor is in forward bias and is switched ON via the application of sufficient gate pulse (trigger). This is made possible by altering the phase angle at which the thyristors are triggered. The inclusion of phase-controlled thyristors in the converter ensures that a variable DC output voltage is obtained. The AC input voltage that goes into a converter is normally at fixed RMS (root mean square) and fixed frequency. It is expressed asįixed Input − Voltage, frequency and AC power

In other words, it is used in the conversion of fixed-frequency and fixed-voltage AC power into variable DC voltage output. Three phase frequency converters, generally for industrial equipments.A phase controlled converter converts AC to DC energy (line commutated). Single phase frequency converters, generally for home appliances There are much more cases we need to convert 50 Hertz to 60 Hertz, or from 60 Hertz to 50 Hertz, in case you are interesting to get one, just shopping on, we are selling: a Canada enterprise making an electric device in India (50 Hertz) and tend to sell the products in USA, Canada (60 Hertz), or a Australia (50 Hertz) enterprise exports electrical appliances to US, Philippines, the company will need a 50 Hertz to 60 Hertz converter (or 60 Hertz to 50 Hertz) to test the appliances' operation compatibility under expected Hertz. USA, Philippines, Peru), and bring some 50 Hertz electric appliances which are not compatible with running on 60 Hertz, or sometimes we just buy a device which is only available for 50 Hertz power system, in such cases, we need a 50 Hertz to 60 Hertz frequency converter to convert Hertz (or vice).Ĭase 2: Some multination enterprises make electrical home appliances, industrial machines outside the selling market countries, e.g. UK, UAE, Malaysia) to another (60 Hertz, e.g.

Why use a 50 Hertz to 60 Hertz Converter?Ĭase 1: When you travel or move from one country (50 Hertz, e.g. By affording this balance of the Volts/Hz/RPM ratio, the motor design criteria is very closely matched in the conversion. For example, if the motor speed at 50 Hertz is 1,400 RPM, dividing the RPM total by 0.8, results in a quotient of 1,750 RPM. Setting the motor speed (RPM) using the 20% factor is also essential. 1.2 hp, with a corresponding increase in torque. This will increase the motor output to approx. Use a 20% factor across the board in the programming.įor example, a motor at 1 hp, 50 Hz, 400V AC, set the motor Hertz in the frequency converter to 60Hz, then the motor voltage to 480V AC.

#AC TO CONVERTER FULL#
I used to set a 50 Hz three phase motor to run on 60 Hz power supply many times per year, using frequency converters capable of full motor speed regulation. The motor would be able to produce rated torque at both 50/60 Hertz frequencies only apply if the V/Hz ratio is constant, meaning that at 50Hz the supply voltage would need to be 380V and at 60Hz the supply voltage would need to be 460V. Since motors are constant torque machines then by applying the formula that HP = ( torque* n)/5252 then you can see that with a 20% increase in speed the motor would also then be able to produce 20% more horsepower. Since the formula for governing the synchronous speed of a three-phase motor is n = (120 * Hz)/ p if this is a 4-pole motor then at 50 Hertz the speed would be 1500 RPM whereas at 60 Hertz the speed would be 1800 RPM. Practices have proved using 50Hz, 60Hz frequencies are appropriate. If the frequency is too low, the electrical equipment's materials will increase, along with heavy and high cost, and will make lights flashing obviously.
#AC TO CONVERTER GENERATOR#
When the frequency increases, the copper and steel consumptions of the generator and transformer decrease, along with the reduction of weight and cost, but will make the inductances of the electrical equipment and transmission line increase, reduce the capacitances and increase losses, thereby reduce the transmission efficiency. For a 2-pole motor, the speed n = 50 * 120 / 2 = 3000rpm for a 4-pole motor, the speed n = 50 * 120 / 4 = 1500rpm. The grid standard frequency is 50Hz, which is a constant value. AC power frequency is determined by the pole number of the generator p and speed n, Hz = p* n/120. The speed of 50 Hertz 2 poles synchronous generator is 3000rpm. The electricity 380V AC and 220V AC, are both 50 Hz frequencies. That means the voltage changes from positive to negative, and from negative to positive voltage, this process converts 50 times/second. 50 Hertz (Hz) means the rotor of the generator turns 50 cycles per second, the current changes 50 times per second back and forth, direction changes 100 times.
