A regulated power supply has a synchronous detector in a voltage regulator feedback loop. The detector is coupled to a secondary of a transformer to detect the AC voltage. The result is faster response time to a step change in the primary voltage and all DC output voltages are constant.

An AC to DC power supply having a multi-channel, flyback inverter output section regulated via a fixed frequency, pulse width modulation controller. The controller indirectly regulates each channel by regulating an auxiliary channel, whereby the duty cycle of a switching transistor in the flyback inverter section is varied to maintain a constant DC voltage on the auxiliary channel and correspondingly on each output channel.

A direct current to alternating current inverter with an output transformer is regulated by a pulse width modulator which alternately closes one of two switches connected with the center tapped primary winding of the output transformer. A synchronizing circuit for the pulse width modulator has means for gating synchronizing pulses to the clock of the modulator, blocking synchronizing signals which would cause an unbalance in the duty cycles of the switches and saturation of the output transformer.

A high integrity multiple output power conditioner operating from redundant dc sources utilizes circuits to combine the sources to share a load and provide source isolation in event of component failure in any one of plural converters employed. Multiple ground planes permit high integrity checking of individual operation of multiple power converters employed in the system.

A high-voltage converter circuit which uses a slip slide power conditioner to reduce non-monotonic non-linearities in the converter output signal is disclosed. The slip slide power conditioner includes: a choke feed D.C. circulator; two radio frequency (RF) power pumps; a phase detector; a phase controller; and a combiner. The choke feed D.C. circulator receives the D.C. input signal and produces therefrom two voltage output signals which are each sent to one of the two RF power pumps. The two RF power pumps produce two out-of-phase square wave output signals which are algebraically combined in the combiner to form an output signal whose amplitude is a function of phase difference. The phase detector and phase controller sample this output signal and adjust the phase of the two power pumps to remove non-linearities due to secondary ranging (resonance) that beats with harmonics of their square wave signals.
