I.  INVERTER

 

A.Topology

The Auto Power Inverter Charge

is built according to the following topology.

Invert: Full Bridge Topology.

Charge: Isolated Boost Topology

When operating in invert mode, the direct current (DC) that enters the inverter from the 

batteries is filtered by a large input capacitor and switched “On” and “Off” by the Metal 

Oxide Silicon Field Effect Transistors (MOSFET) at a rate of 50 Hz or 60Hz, and directed 

into the transformer which steps the voltage up to 230 or 120 volts. The unit has a 16bit, 

4.9MHZ microprocessor to control the output voltage and frequency as the DC input volt-

age and/or output load varies.

Because of high efficiency MOSFETs and the heavy transformers, it outputs PURE SINE 

WAVE AC with an average THD of 7% (min 3%, max 10% under full linear loads) depend

-

ing on load connected and battery voltage.

The peak invert efficiency of Inverter is 80%.

B.Overload Capacity

The Auto Power Inverter Charger 

has different overload capacities, making it ideal to handle de

-

manding loads.

1. 

For 110%<Load<125%(±10%), no audible alarm in 14 minutes, beeps 0.5s every 1s in the   

 

   15th minute, and Fault(Turn off) after the 15th minute.

2

. For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after the 1 minute.

3

  For 300% <Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.
