within triacs diodes block 24 are adapted to switch into an off state under the control of waveform chopping switch 16 and to prevent signals from being applied to converter outport port 26 during portions of both the positive going cycles and the negative going cycles of the input ac waveform this results in power conversion of an input ac signal while still providing an output signal having substantially the same frequency as the input which is suitable for application to a load device having electronic components therein referring now to fig2 4 there are shown input power waveform 40 intermediate power waveform 50 and converted output power waveform 60 respectively each of the power waveforms 40 50 60 has a positive half cycle 42 and a negative half cycle 44 the frequency shape power and phase of output power waveform 60 substantially follows those of input power waveform 40 allowing for minor differences the minor differences can be due to factors such as loss noise and artifacts that may be introduced by electronic power converter 10 input power waveform 40 is applied to converter input port 12 for conversion by electronic power converter 10 of the present invention intermediate power waveform 50 is then created within triacs diodes block 24 of electronic power converter 10 in accordance with waveform chopping switch 16 as part of the power conversion process of the present invention converted output power waveform 60 is the output ac waveform of electronic power converter 10 which is provided at converter outport port 26 in order to convert input power waveform 40 into output power waveform.
