2.2.2. Charger/Booster A. The charger/booster utilizes solid state Pulse Width Modulation (PWM) controlled Insulated Gate Bipolar Transistors (IGBT). The charger switching frequency is 10kHz, and the booster switching frequency 2kHz. B. The Battery Charge Current charger logic and control circuit DC battery current limiting function enables controlled battery charging. The battery charge current limit will control the recharge current by reducing the rectifier/charger output when the set limit is reached.
H. Battery Self Test (Diamond-Sense); for a short duration, a small power discharge from the battery is automatically performed. The UPS module, from this small power discharge, evaluates the degradation of the system battery. The following advantages are achieved: 1. The Diamond-Sense Battery Self-Test function can be performed even when load is on inverter. 2. Due to the short duration small power discharge, there is no effect to battery life expectancy. 3.
a. Field Programmable Gate Array (FPGA) Control b. DSP based Control c. DSP Sampling Frequency is 30 kHz, therefore the control samples 500 times in 1 cycle of output voltage. Output voltage is controlled with high precision. B. Voltage Regulation The inverter output voltage shall not deviate by more than +/- 1% RMS with the following steady state conditions: 1. 0 to 100% loading. 2.

The need for additional filtering to limit the harmonic content shall not be required. Therefore high efficiency, reliability and original equipment footprint are maintained. H.
purpose of this feature is to compensate for varying line drop voltage between the inverter and the critical load M. Inverter Operation Inhibit The external dry contact can inhibit the inverter operation. When UPS condition is load on inverter, load is transferred to bypass. 2.2.4.
