Page 5: I Ntroduction
1 I ntroduction EP series is a line interactive power system that has a step wave output. It prevents impulse, surge, sag and power outage situations. It provides the UPS output load with a reliable source. It has the following functions: Boost: If the utility voltage drops to line boost activated point*, the AVR will be activated and increase the input voltage by 1.18 times of incoming utility voltage.
Page 6: Block Diagram
2 Block Diagram The Block diagram of Vesta series (refer to Figure S-1) is divided into the following parts: 2.1 Main Relay ( MAI N-RY) : It's to switch the UPS between line mode and battery mode. 2.2 Boost Relay ( BOOST-RY) : At line mode, this is a switch used to boost UPS output voltage 18% when the utility voltage is under line boost activated point.

Provide + 5Vdc (generated from 7805 regulator) and + 12Vdc power supply. Charger: The source for the Charger comes from the mains through the transformer and full-bridge inverter.
Page 8: Control Pow Er Circuit
Control pow er circuit The control power (+ 12Vdc and + 5Vdc) comes from the following sources (Figure S-2). Start w ithout input AC pow er ( Cold start) : A "Cold start "is described as follows: 3.1.1 When "ON/ OFF" switch (SW1) is pressed, a positive battery current flows through SW1 to charge C15.

Page 10: Battery Charger
4 Battery Charger The flow chart of charger is described as follows: (Figure S-3-A & Figure S-3-B) 4.1 When UPS is connected to the utility, the control power (+ 5Vdc) will be established and the CPU will start to work. 4.2 When CPU turns on Main Relay (RY01), the AC power flows into Main Transformer.

Page 12: Line And Zero-Crossing Detection
5 Line and Zero-Crossing Detection Please refer Figure S-4 5.1 Line Detection The input voltage is fully rectified and generates a signal. The signal will be sent to pin 11 of CPU through a voltage divider at R45, R45A and R40// R47. By monitoring this rectified sinusoidal voltage, the CPU can identify if the utility is normal or abnormal.

Page 14: I Nverter Operation
6 I nverter Operation The Inverter circuit (Figure S-5-A and Figure S-5-B) and PWM control are only active under Battery mode. The Inverter circuit of Vesta is based on a full-Bridge circuitry and its output is driven by a transistor which is controlled by CPU. Refer to the Inverter circuit diagram, the CPU.M1, CPU.M2, CPU.M3, and CPU.M4 signals are generated by CPU.

Page 17: Active Clamp
7 Active Clamp The purpose of Clamp is to pull down the output voltage while two sets of Inverter MOSFET are OFF. The Clamp effect is active during the period of 0Vac at battery mode. CLAMP principle is shown in the last paragraph of Chapter 6 Inverter Operation. Page 16 of 28 Rev.
Page 18: Microprocessor( Cpu) Control Circuit
8 Microprocessor( CPU) Control Circuit The CPU is supplied by + 5Vdc power supply to pin7 with ground pin at pin3. An extra oscillation circuitry consisting of C01, C02, and crystal XL1 is connected to pin4 &5. The Vesta series is using MOTOROLA/ MC68HC908JL8CSP CPU. The pin definition is listed below (Refer to Figure S-6 CPU control circuit): PI N FUNCTI ON...
