A digital phase converter uses a rectifier and inverter to create a third leg of power, which is added to the two legs of the single-phase source to create three-phase power. Unlike a phase-converting VFD, it cannot vary the frequency and motor speed, since it generates only one leg.

The digital phase converter takes the AC power from your panel, converts it into DC, and then recreates the AC waves from scratch. Building the 3 phase power from scratch by going through this AC-DC-AC transformation allows the phase converter to specifically tailor the 3 phase power output.

Digital Phase Converter uses a double conversion technique where the input rectifier (which consists of IGBTs in series with inductors) converts AC (Alternate Current) power from utilities into DC current and then back to the AC. Insulated Gate Bipolar Transistors (IGBTs) are controlled by software in the DSP (Digital Signal Processor).

Our digital phase converters are designed to power high inertia and high friction loads such as pumps, fans, and compressors while maintaining the balanced power necessary to run voltage-sensitive equipment like CNC machines.
