Change frequency power
The VFP frequency conversion power is the new generation 32 bit processor of ARM, which is used by Xun Chang company as the core. IGBT is the executive component, and the isolation transformer is designed for voltage conversion.


It uses the AC-DC-AC (AC - DC - AC) mode to convert the input power into any power supply in the world through the SPWM (sinusoidal pulse width modulation) transformation to meet the needs of different voltages and frequencies.
