Cncelegroup Adjustment

In switching regulators and switched capacitor converters using an internal oscillator to set the switching frequency of the output transistor. The value of the switching air circuit breaker‍ frequency can be determined in some external components used in the converter, to determine the frequency of the noise generated by the converter, and the impact performance of the converter. Some converter allows to adjust the internal oscillator frequency ("frequency adjustment") or by synchronizing oscillator with an external power supply ("sync") to change the switching frequency. Generally, by increasing the switching frequency, with smaller parts (capacitors, inductors) in the converter output stage. This may reduce the efficiency of the converter, because of the increased switching losses, unless while using higher quality components. Good performance higher frequency than the lower frequency converter converter has a faster transient response. Electric transformer‍ If a board has several converters, it is often best to sync them to a common source. It can control the noise generated by the entire batch, and to minimize any "tapping frequency" may arise. This problem is usually very important for high-power converter (e.g. power 5W or higher). In many cases, the switching frequency can increase from its preset value. Product data sheets will mark the frequency range of the function.

Capacity curve

Auto regulator (single-phase 0.5kVA ~ 3kVA, 10k and below the horizontal, three-phase 9kVA and below) when the input voltage drops below 198V, output capacity began to decline; when the input voltage is equal to 160V, down to 50% of the rated capacity of the regulator. Therefore, the lower end of the supply voltage with particular Voltage stabilizer‍ attention to lighten the load derating, so as not to overload the regulator burned;
