Sine Wave Inverter

Product Overview

 The sine wave inverter we have developed uses a number of power semiconductors of our own manufacture to obtain high efficiency. It utilizes digital technology with a CPU, provides electronic governor functionality to hold the engine's rpm constant, and offers a high-quality AC sine wave.


Use and Compatibility
Use
Low-acoustic-noise portable generators
Compatible Products
1 kVA to 3 kVA model--output voltage rated AC100 V /120 V/220 V/230 V
Features

■ Uses our own highly reliable semiconductors are used in the AC output part.
   The high dv/dt tolerance MOS FETs we manufacture bring high reliability.
■ Structure
 Our sine wave inverter is composed of three blocks: a converter part that converts input AC voltage to DC voltage, an inverter part
  that converts DC voltage to AC voltage, and a filter part that makes the PWM waveform into a sine waveform. It uses digital control
  by CPU throughout: AC voltage (3φ input) → DC voltage (voltage held constant) → AC voltage (voltage held constant). The
  inverter's circuit structure has also been simplified to improve efficiency.
Power Semiconductors of our own manufacture
■ 3 types of power semiconductors installed--thyristors, diodes, and MOS FETs  To Semiconductors
