Filed: 1990-12-13
Abstract: PURPOSE:To improve control characteristic by regulating the switching frequency of a primary driving circuit in the vicinity of the resonance frequency of an electromechanical conversion transformer thereby regulating the output of a converter. CONSTITUTION:High frequency power is taken out from the secondary of a piezoelectric transformer 2 and converted through an output rectifying circuit 3 into DC power which is then fed to a load.

A piezoelectric transformer 1 incorporates a resonance circuit and the DC power to be fed to the secondary has maximum magnitude when the switching frequency of the input power to the primary of the piezoelectric transformer 1 is equal to the resonance frequency. The variable frequency oscillator 5 is regulated to normally shift the frequency of high frequency AC output power of a primary driving circuit 1 slightly from the resonance frequency and the output voltage is fed back through the detecting/amplifying circuit 4 and thereby bringing the frequency of the primary driving circuit 1 close to the resonance frequency or separating therefrom thus regulating the output voltage.
