Title: Active filter
Inventor: ICHIKAWA FUMITOSHI
IPC: H02J3/01
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: Toenable control of higher-order harmonic current which was impossible in prior out. SOLUTION: There is control delay in the control system of an active filter. Higher-order harmonic current can be controlled by controlling current early by a time equivalent to the control delay. In general, harmonic current component which flows to a load in a power system slowly varies, and the waveform does not vary so much up to the preceding several periods. Therefore, current can be controlled by using as a current command value data (n-α) periods ago, obtained by making the phase of the current detection data n periods ago (n: 1, 2, 3,...8 or so) by an amount equivalent to the control delay α(1>α>0). For this reason, a ring buffer is placed between a compensation current detection system and the current control system.  The compensation current detection system writes the compensation current into the ring buffer, and the current control system reads the current waveform of a pointer (n-α) periods ago, that is, with its phase advanced by αperiods on the ring buffer, as a current command value ahead by α. Thus feed forward-like current control is exercised.

Abstract: PURPOSE: To prevent the generation of noises at the output side of a mixing circuit, which is receptive of musical scale signals, due to the DC fluctuations by applying a DC potential as a bias to the mixing circuit.  
     CONSTITUTION: Forty eight circuit blocks 101 to 412 are arranged to correspond to the respective intersectios of a matrix 1 having a key switch 4. A ring counter 8 receives clocks fc to generate scanning pulses ϕ 1  to ϕ 4  so that the row of the matix 1 may be scanned through buffer amplifiers 9 to 12.
