DC to AC Inverter is used to convert the input DC power into AC output power at desired output voltage and frequency. The AC output voltage could be a fixed or variable frequency. The DC input power to the inverter may be from a battery, fuel cell, solar cell, SMPS, or other DC sources. This conversion process is achieved utilizing controlled power transistor switching devices such as BJTs, MOSFETs, IGBTs, MCTs, SITs, and GTOs.

Key features of DC to AC Inverter

  • True sine wave output.
  • High efficiency.
  • Built-in remote ON-OFF control.
  • Battery low alarm.
  • Battery low shutdown.
  • Over-voltage protection.
  • Overload protection.
  • Output short circuit protection.
  • Input reverse polarity protection.
  • Thermal protection.  

DC to AC inverters are ideal for use in all types of utility loads such as home appliances, power tools, office equipment, and portable equipment, adjustable speed AC drives, induction heating, vehicles, stand by aircraft power supplies, UPS (Uninterruptible Power Supplies) for computers, solar power, and HVDC system.
