Abstract:
There is described herein a direct current power supply which offers improved control over an output signal. An input signal generated by an alternating current source is received and chopped by a solid state relay. The chopped signal is rectified by a bridge rectifier before being filtered by an “LC” (induction coil-capacitor) or “CLC” (capacitor-induction coil-capacitor) filter. The output signal can then be used as a direct current power supply signal. This power supply may be used in various types of ozone generation systems.

Abstract:
The present invention relates to a hybrid power supply for converting an alternating input signal fed to its input into a direct output signal produced at its output. The hybrid power supply comprises a rectifier for converting the alternating input signal into a mono-alternation signal; a capacitor for smoothing the mono-alternation signal into a direct signal; a switching regulator stage coupled to the capacitor for generating a pre-regulated direct signal having a constant amplitude; a 1/X frequency modulating circuit for generating two switching pulsed signals of constant pulse width at a variable frequency according to a 1/X function in relation to the direct signal originating from the capacitor; and a linear regulator stage coupled to the switching regulator stage for regulating the pre-regulated direct signal, and for generating the direct output signal. A 1/X pulse with modulating circuit can also be provided for generating two variable pulse width signals synchronized with the switching pulsed signals for allowing adjustment of the output. Low power dissipation of the power supply elements allow to use an airtight shielding to eliminates interferences.
Abstract:
A sinewave inverter for converting unstable DC voltage from a variable source such as batteries, fuel cells, wind mills and the like into a distortionless sinusoidal AC voltage of constant amplitude and constant frequency is provided. This pure sinewave inverter with line and load regulated voltage is obtained by using a combination of a hyperbolic frequency modulator with a sinusoidal pulsewidth modulator in the inverter circuit.
