A microcomputer detects and determines whether a problem exists in a power supply breaker of an ECU functioning as a motor controller. Specifically, the microcomputer determines whether there is a malfunction caused by a short circuit in a first FET based on the output voltage and output voltage that are detected in a first FET and a second FET, respectively, when the switching states of the first and second FETs are both off. Afterwards, the microcomputer determines whether there is a malfunction caused by a break in the first FET based on the output voltages of the first and second FETs that are detected when only the first FET is switched on. If the microcomputer determines that the first FET is free from any malfunction, the microcomputer determines whether there is a malfunction caused by a short circuit or a break in the second FET by comparing the output voltage of the first FET and a charge voltage of a smoothing capacitor that are detected afterwards.

The input to the multi-carrier amplifier is modified by a Crest Factor reduction circuit, prior to being applied to the amplifier. The Crest Factor reduction circuit clips the amplitude of the signal, converts the clipped signal to baseband to produce the baseband representative of each carrier, filters each baseband representative to remove the unwanted signals, up converts each baseband representative to its multi-carrier baseband frequency and finally the up converted signals are combined to produce the multi-carrier baseband signal. The input to the Crest Factor reduction circuit could be a baseband, an intermediate frequency (IF) or radio frequency (RF) signal. The Crest Factor reduction could be performed in digital or analog domain.
