Title: Power converter
Inventor: KANEKO KOICHI
IPC: H02M7/48
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To improve an output voltage waveform with the minimum switching times by making an output frequency of a chopping wave generating means variable according to a deviation signal when the deviation signal which is the deviation of an instantaneous output voltage detected value of a power converter from an instantaneous output voltage reference value exceeds a predetermined value. SOLUTION: A voltage signal of a load 4 and a voltage standard which is an output voltage of a reference voltage setting device 12 are added by an adder 31 and an output signal of the adder 31 is sent to an error amplifier 33 through an absolute value converter circuit 32 which converts a signal to an absolute value and then a signal which has been error-amplified by the error amplifier 33 is sent to a function generating means 34. According to an output signal of the function generating means 34, an output frequency of a chopping wave generating means 15 can be varied. By this method, when a non-linear load is connected, the number of switchings is increased at a point in one cycle where a rate of change in current is large and an output voltage waveform deforms and thereby the output voltage waveform can be improved with the minimum number of switchings.

Abstract: PURPOSE:To enable an antenna to receive a weak microwave signal by fitting a microstrip antenna to a vehicle window glass plate and forming a prescribed conductor pattern to the window glass plate in the vicinity of a radiation element. CONSTITUTION:A module 1 is fitted to one side of a window glass 2 and a conductor film 3 made of plural silver conductor patterns is formed to one side of the window glass plate 2 in the vicinity of the module 1.

Abstract: PURPOSE:To enable inexpensive mutual simultaneous calling without fail by linking an antenna conductor with an opened acoustic waveguide tube to the sound collection hole of a receiver microphone through an insulating distance tube at a base part of a box body installation. CONSTITUTION:With the uniform acoustic waveguide tube diameter by a tube antenna electric conductor 20, the acoustic transmission loss is small and the built-in microphone 21 can collect sounds located in the opening edge of the antenna conductor 20.
