Output terminal suspended or unloaded; output terminal over-light load, lighter than 10% of the rated load; input voltage too high or interference voltage. For these issues, adjustments can be made to the output terminal load or the input voltage scale, as detailed below: Ensure the output terminal is not less than 10% of the rated load; if there is an unloaded condition in the practical circuit operation, connect a dummy load of 10% of the rated power in parallel to the output terminal; replace with an appropriate input voltage size, and consider connecting a TVS diode or voltage regulator in parallel at the input terminal when interference voltage is present. Output voltage too low: For abnormal output parameters of the inverter power supply model - output voltage too low. This may cause the entire system to operate abnormally, such as the microcontroller system, sudden increase in load will pull down the supply voltage of the microcontroller, which is easy to cause reset. Moreover, the inverter power supply operating for a long time under low input voltage conditions will greatly reduce the lifespan of the circuit. 36V aviation power supply, 400HZ frequency conversion power supply, 115/200V power supply, 27V DC power supply, 400HZ power supply, aviation power supply
The issue of low output voltage is not to be overlooked. What are the common causes of low output voltage? Low input voltage or insufficient power; excessively long or thin output lines, resulting in excessive line losses; excessively high forward voltage drop of the reverse-connection diode at the input; and an overly large input filter inductor. To address these issues, adjustments to the power supply or replacement of the peripheral circuitry can improve the situation, as detailed below: Increase the voltage or switch to a power input inverter; adjust the wiring, increase the conductor cross-sectional area or shorten the wire length to reduce internal resistance; replace with diodes with lower forward voltage drop; decrease the filter inductor value or reduce the inductor's internal resistance. Excessive Output Noise — In the case of abnormal output parameters of the inverter power supply model — excessive output ripple noise.
