POWER SUPPLY DEVICE, OUTDOOR UNIT, AND AIR CONDITIONER
摘要
<p>Provided is a power supply device capable of applying N-phase N-wire type power supply to the load corresponding to N-phase (N + 1) wire type power supply and dealing with different voltages. Output lines of power supply (E1) are connected to inverters (32, 33) through a three-phase full wave rectifier circuit (31). Further, the output lines from the power supply (E1) are connected to a transformer (20). The transformer is provided with coils (21 to 23). The coils (21 to 23) are connected at one ends with the output lines of the power supply (E1) and the other ends with a neutral point (NP) in common. The output lines are drawn from in the middle of the coils (21 to 23) through taps. Each of the voltages between the output lines and the neutral point (NP) is supplied to a load (50).</p>
