What is a digital generator? Analysis of system throttle control

Digital generator is a new generator product field developed in recent years. The popularization of this product is mainly concentrated on the traditional generator products of small generator systems below 5 kW, mainly using low speed engines to drive a power frequency output. The generator works normally and directly outputs the corresponding required power supply. This type of system has a relatively large volume due to the starting operation at a lower speed, and at the same time, for the generator, the low-speed generator It is also difficult to make the volume small, and it is difficult to miniaturize and portify the entire system. Due to the quality of the output power supply

Digital generators are a new field of generator products developed in recent years. The popularization of this product is mainly concentrated on small generator systems below 5 kW.

The traditional generator products mainly use a low-speed engine to drive a power frequency output generator for normal operation, and directly output the corresponding required power supply. This type of system, due to the starting work at a lower speed, results in a relative volume. At the same time, for the generator, the volume of the low-speed generator is also difficult to reduce the size, making it difficult to miniaturize and portline the entire system.

In the quality of the output power supply, the voltage and frequency of the output power supply are proportional to the engine speed. The fluctuation of the system speed under the different load conditions will directly affect the stability of the output power supply voltage and frequency. The waveform of the power supply is directly affected by the generator. Generally, the TDH of the output waveform of this type of generator of low power is not ideal.

The generation of digital generator solutions has made these problems well solved.

Digital Generator Controller Product Description

The controller product of advanced power inverter technology and control technology, the output waveform is a standard sine wave, the specific waveform is as follows:

The software closed-loop control technology is adopted on the system power output. Compared with the conventional hardware control method, the product has high utilization efficiency of the engine output power, so that the equivalent engine system can have higher system output utilization efficiency.

Compared with the traditional generator system, the output waveform of the control system in the full power output stage is sinusoidal, and the output power quality is high and the stability is good.
