When the output current reaches the set value, the power supply enters the constant current mode (C.C), the indicator (C.C) on the front panel lights up, the current output will be constant at the preset value, and the output voltage will change with the load.
SECTION 263353 - STATIC UNINTERRUPTIBLE POWER SUPPLY
Abnormal Supply Conditions: When normal AC supply deviates from specified voltage, waveform or frequency limits, the battery supplies energy to maintain constant inverter output to the load. When normal power fails, energy supplied by the battery through the inverter continues supply to the load without switching or disturbance.

The output power for various input power and Output Power has been shown in Fig.8(a).It is absorbed that the power drawn decays steeply for lower load and as the load increases the power drawn gradually decreases and remain constant at greater loads. It is also seen that the proposed new control strategy has less load Sensitivity. The results obtained indicate that the FLC based CLL-T SPRC is ...

This refers to a power supply reaching a state of nearly constant voltage and nearly constant current output after at least 30 seconds of operation at a given load. Total Harmonic Distortion (THD) THD is the ratio, expressed as a percent, of the rms value of an AC signal after the fundamental component is removed to the rms value of the fundamental component. For example, THD of current can be ...

A switching power supply is used to isolate the IC’s VCC pin. The TPS54060 buck converter produces 8.5 V VCC from the high voltage input. The VCC bias supply also powers the external half bridge gate driver, pre-charge circuit, current sense circuit and OPAMP buffer. Any switching power supply capable of operating from the system’s maximum required input voltage that can generate an 8-14 V ...
