    • A COM-type power supply having a separate V(Voltage)-sensing circuit for each channel is provided to implement a power supply for high precision control at low cost by compensating DC voltage of a minute value outputted to each channel. A COM-type power supply having a separate V-sensing circuit for each channel includes a bridge rectifying unit(130), a voltage main rectifying unit(200), an output terminal(140), a signal sensing input terminal(160), a voltage sensing circuit(170), a reference voltage generation unit(180), and a control unit(190). The bridge rectifying unit(130) converts AC power applied to each of first and second output channels into DC power through bridge rectifying. A voltage main rectifying unit(200) controls DC voltage and current outputted to each channel. The output terminal(140) outputs the final DC power of each channel. The signal sensing input terminal(160) is connected to a load connected to an output terminal, and receives the output DC power. The voltage sensing circuit(170) senses the DC power inputted from the sensing input terminal(160), and removes inputted external noise. The voltage sensing circuit(170) stabilizes a distorted signal and performs final phase correction. The reference voltage generation unit(180) generates a constant voltage reference value to vary a DC voltage value outputted through each channel. The control unit(190) determines a final output voltage outputted to the output terminal by comparing a signal outputted from the reference voltage generation unit(180) with a signal outputted to the voltage sensing circuit(170). An output minus terminal of a first output channel and an output plus terminal of a second output channel are connected to a common terminal(150).
