Claim 0:
1. A rectifier comprising:
n (n is a natural number of 2 or larger) sets of series circuits in each of which a positive electrode side semiconductor device to be connected with a positive electrode side output terminal and a negative electrode side semiconductor device to be connected with a negative electrode side output terminal are connected in series with each other and a series-connection connection point is connected with a corresponding AC power source,
wherein each of the positive electrode side semiconductor device and the negative electrode side semiconductor device has at least a rectification function of making a current flow from a negative electrode side to a positive electrode side,
wherein in each of the n sets, one of the positive electrode side semiconductor device and the negative electrode side semiconductor device is a MOSFET,
wherein in at least one of the n sets, the other one of the positive electrode side semiconductor device and the negative electrode side semiconductor device is a specific diode,
wherein the specific diode is a Schottky barrier diode, and
wherein a breakdown voltage of the Schottky barrier diode is lower than a clamp voltage of the MOSFET.
