摘要： The present invention is a system and method for a direct conversion programmable power source controller. The invention uses a sampling rate optimized for a transformer used to isolate or to step up or step down the power. The power is sampled at the source frequency and that sampling is phase-angle modulated according to a modulating signal at a frequency representing the sum of the frequencies of the power source and the desired output. After passing the power through the transformer, the invention then again chops that power to produce a multiplication of the power sinusoid with the modulation sinusoid. The output is filtered to integrate the waveform and fed to a load in delta. Between any two terminals of the delta connection, the output voltage presents as a well-formed sinusoid of controlled amplitude and frequency.

摘要： A 3-phase-to-3-phase power converter is intended to control the output voltage and current so as to provide a 3-phase sinusoidal wave which is controlled in compliance with the input voltage. The main circuit has a switching period shorter than 30.degree. of the power voltage waveform and it is controlled so that switching of lines takes place in alternate fashion, whereby the input power factor is improved.

摘要： In a pulse-width modulated unrestricted frequency changer (UFC) the harmonic contents of the input current are minimized by splitting the active time intervals within the fundamental time frame into at least two pulses which are located within such time frame and controlled in width as if individual PWM single-pulse UFC's were controlled having a phase shift between each other so as to eliminate or reduce undesired frequency components. Such elimination or minimization of selected frequency components is used to reduce the size of the lowpass filter at the input of the UFC, namely by allowing a higher cut-off resonance limit.
摘要翻译：在脉冲宽度调制的无限制频率变换器（UFC）中，通过将基本时间帧内的有效时间间隔分成至少两个脉冲，使输入电流的谐波内容最小化，这两个脉冲位于这样的时间范围内，如图单个PWM单脉冲UFC被控制为具有彼此之间的相移，以便消除或减少不期望的频率分量。使用所选频率分量的这种消除或最小化来减小在UFC的输入处的低通滤波器的尺寸，即通过允许更高的截止共振极限。

摘要： The present invention provides a digital gate pulse generator (1) which controls the output of a cycloconverter used for electrical power conversion applications by determining the timing and delivery of the firing pulses (12) to the switching devices (A₁-A₆) in the cycloconverter. The gate pulse generator (1) of the present invention utilizes digital techniques and a predetermined series of values (6) to develop the necessary timing signals (9) for firing the switching devices (A₁-A₆). Each timing signal (9) is compared with a reference signal (13) to determine the exact firing time.
