Representative image1PH - 3PH Inverters
A power inverter converts DC input (from batteries, rectifiers, solar arrays or a DC bus) into clean, regulated single-phase or three-phase AC at a controlled voltage and frequency.
Overview
A power inverter converts DC input (from batteries, rectifiers, solar arrays or a DC bus) into clean, regulated single-phase or three-phase AC at a controlled voltage and frequency. ACE's units are IGBT-based and use high-frequency PWM switching to synthesise a low-distortion sine-wave output, making them suitable for powering motors, drives and sensitive industrial loads from a DC source. Buyers choose these inverters for high conversion efficiency, tight output voltage/frequency regulation, low THD and the flexibility of either 1-phase or 3-phase output. The standard parameter set below reflects the general industrial inverter class; ACE configures rating, DC input window and output to the application rather than offering fixed catalog SKUs.
Specifications
| Output phases | single-phase or three-phase (1PH / 3PH) |
|---|---|
| Power rating | typically ~1 kVA to 100+ kVA (class range; ACE builds to order) |
| Switching device | IGBT, high-frequency PWM control |
| Output waveform | pure sine wave |
| Output voltage | e.g. 230 V (1PH) / 415 V (3PH), typically regulated to ~±1% |
| Output frequency | 50 Hz / 60 Hz (selectable; 400 Hz available in some classes) |
| DC input voltage | configured to battery/DC-bus (e.g. 110/220/360/384 V DC class) |
| Output THD | typically < 3% at linear load (IEEE-519 class) |
| Efficiency | typically ≥ 90-95% |
| Cooling | forced-air (lower kVA) / liquid or fan-cooled (higher kVA) |
| Protections | overload, short-circuit, over/under-voltage, over-temperature |
Applications
- DC-bus / battery-backed AC supply for industrial loads
- Motor and variable-speed drive supply from a DC source
- Backup and standby AC power
- Renewable / solar and storage power conversion
- Powering sensitive equipment requiring clean sine-wave AC
