Ripple coefficient test
When the charging device is in a floating charging (stabilized) state, the AC input voltage changes within a range of + exceeding its rated value, the output current changes within a range of ~ of its rated value, and the output voltage At any value within the floating charge voltage adjustment range, the ripple coefficient measured at both ends of the resistive load should comply with the requirements in the table. The ripple coefficient is calculated using the following formula
/
where the ripple coefficient
is the peak value of DC voltage pulsation
is the valley value of DC voltage pulsation
is the average value of DC voltage.
Parallel current sharing test of high-frequency switching power supply modules
Set the output voltage of all modules of the equipment to the same value within the floating charging voltage adjustment range, all modules are put in, and during float charging (voltage stabilization) running in the state. Assume the total number of modules is +, and the module outputs rated current.
Adjust the load so that the output current of the device is the rated value [(+)]. Measure the output current of each module and calculate its current-sharing unbalance. Adjust the load so that the output current of the device is the rated value (+) Measure the output current of each module and calculate its current-sharing unbalance. Its value should comply with the regulations. Use the following calculation formula to calculate the current-sharing unbalance (module Output current limit value (average value of module output current)/module rated current value
When the output current of the device is , take one module out of operation, measure the output current of the remaining modules, and calculate its current-sharing unbalance. Its value should meet the requirements.
